Good, but not unexpected, news for the Private Investor portfolio was the trading update from Murray & Roberts on Friday. According to the update, fully diluted headline earnings for the financial year ended June 30 this year are expected to be between 60% and 70% higher than the comparable figure last year. When the half-year interim results were published in February, the directors wrote that they expected fully diluted headline earnings for the full year to June 30 this year to grow between 50% and 60% .

The difference between 50% and 60% is, as you know, 20%; the difference between 50% and 70% is 40%. My reason for mentioning this is to emphasise how in such a short period (in this case some five months) a company's management can have to alter its earnings forecast radically. I also mention it to show how wide the disparity on a forecast range can be.

In the financial year 2007, M&R's fully diluted headline earnings per share were 325c.

Based on the prospects in the report on the first half of this financial year, shareholders could have expected a full year's diluted headline earnings per share of between 488c and 520c. Based on the latest trading update, the outcome could be between 520c and 553c.

In August last year, the Private Investor portfolio bought 140 shares, a total investment of R9 951,83 at an average cost of R71,08 including transaction costs. I guesstimated that fully diluted headline earnings per share would be 300c for the financial year ended June 30 last year.

At the share price of R71,08, and the actual fully diluted headline earnings per share of 325c, the earnings yield of the financial year 2007 was 4,6%, the price:earnings ratio was 21,8 and the dividend yield was 2,3%. Assuming no change in earnings this year, last year's historic ratings were what the Private Investor portfolio expected to enjoy.

But, of course, Jean and I bought M&R because we expected around 40% to 50%, and we're going to enjoy even more. My middle-of-the-road guesstimate on fully diluted headline earnings per share for the financial year 2008 is 545c. The financial year has already ended and so, we're assuming our shares have earned a yield of 7,7%. Its dividend yield for the year is expected to be 3,8% but, as we received the final dividend for last year - a bit of lucky timing - our actual dividend yield is probably closer to 4,7%. The assumed historic price-earnings ratio is 13. The magic of earnings growth is amazing, isn't it?

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 with a proposed AD. The proposed AD applies to Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, "Parallel Valve" reciprocating engines, with certain Engine Components Inc. (ECi) cylinder assemblies, part number (P/N) AEL65102 series "Titan", installed. We published the proposed AD in the Federal Register on May 19, 2008 (73 FR 28756). That action proposed to require initial and repetitive visual inspections and compression tests to detect cracks at the head-to-barrel interface, replacement of cylinder assemblies found cracked, and replacement of certain cylinder assemblies, at new reduced times-in-service.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is provided in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the comments received.

Request To Reduce the Economic Impact

One commenter, the Aircraft Owners and Pilots Association, states that the 50-hour inspection interval should be increased to 100 hours, to reduce the economic impact of the cylinder assembly inspections. Another commenter, a private citizen, states that the cost of the 50-hour inspections was not considered in the NPRM economic estimate.

We do not agree. We selected the 50-hour inspection interval so that aluminum cylinder cracks could be detected before a head separation occurred. By removing leaking cylinder heads discovered during the periodic 50-hour inspections, the probability of having an in flight head separation is greatly reduced. Also, the 50-hour inspection interval coincides with the scheduled maintenance for normal engine oil and filter changes. Also, the costs of compliance in the NPRM did include costs for the additional cylinder assembly inspections. We did not change the AD.

Retiring Cylinder Assemblies at Time-Between-Overhaul Is Too Expensive

One commenter, a private citizen, states that it is too expensive to retire all the subject cylinder assemblies at the normal overhaul time. Another commenter, a private citizen, states that it is unreasonable for general aviation airplane owners, in Part 91 use, to be required to retire cylinder assemblies at the time-between-overhaul or at normal engine overhaul time.

We do not agree. The subject cylinder assemblies can be safely run to the normal TBO with the required 50-hour inspections, with compression tests. Because of metallurgical analysis results of the fatigue cracks in the aluminum alloy cylinder heads, and also the history of the head separation hours-in-service, the probability of a head separation is greater with the subject cylinder assemblies running past the time-between-overhaul time. Therefore, we do not consider the cylinder assemblies to be airworthy past the normal engine overhaul time. We did not change the AD.

[Page Number 53106]

Cylinder Assembly Serial Number Range Is Different in the ECi Mandatory Service Bulletin

One commenter, ECi., states that the cylinder assembly serial number range in the proposed AD for the Group "B" cylinders is slightly different from the serial numbers listed in the ECi Mandatory service Bulletin No. 08-1. The commenter states that several additional cylinder serial numbers should be included in Group "B".

We do not agree. We researched the cylinder assembly serial numbers in the proposed AD and they are correct. The Group "A" cylinder assemblies go up to serial number 35171-22. The Group "B" cylinder assemblies start at serial number 35239-01. We discussed the serial number comment with ECi. They agree that the serial number range in the proposed AD is correct. ECi states that they have revised the serial numbers in ECi. Mandatory Service Bulletin (MSB) No. 08-1 to match the serial numbers in the AD, and issued MSB No. 08-1, Revision 3, dated August 19, 2008. We now reference this MSB Revision 3 in the AD.

Conclusion

We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD as proposed. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

We estimate that this AD will affect 13,000 ECi cylinder assemblies installed in aircraft of U.S. registry. The visual inspection and compression tests will take about 4 work-hours for each engine. An individual cylinder replacement will require $1,100 for parts and 6 work-hours. Lycoming engines with a set of 4 ECi cylinders will require 12 work-hours for the cylinder replacement. Lycoming engines with a set of 6 ECi cylinders will require 16 work-hours for the cylinder replacement. We estimate 18 percent of the affected population of cylinders will be replaced. We estimate the total cost of the AD to U.S. operators to be $7,952,000. Our estimate is exclusive of any possible warranty coverage.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, "General requirements." Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

(1) Is not a "significant regulatory action" under Executive Order 12866;

(2) Is not a "significant rule" under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

We prepared a summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary at the address listed under ADDRESSES.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

[Section] 39.13 [Amended]

2. The FAA amends [Section] 39.13 by adding the following new airworthiness directive:

2008-19-05 Engine Components, Inc. (ECi): Amendment 39-15672. Docket No. FAA- 2008-0052; Directorate Identifier 2008-NE-01-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective October 20, 2008.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, "Parallel Valve", reciprocating engines listed in Table 1 of this AD, with ECi cylinder assembly, part number (P/N) AEL65102 series "Titan", and with cylinder head, P/N AEL85099, installed.

(1) The applicable cylinder assembly serial numbers (SNs) are SN 1138-02 through SN 35171-22, (referred to in this AD as Group "A" cylinder assemblies); and

(2) SN 35239-01 through SN 37016-28 (referred to in this AD as Group "B" cylinder assemblies).

(3) Note that the cylinder assembly P/N is at the crankcase end of the cylinder assembly, and might be difficult to see. As a guide in determining if your cylinder assemblies are affected, all affected cylinder assemblies have cylinder head P/N AEL85099. The cylinder head P/N is at the top of the cylinder head, near the intake and exhaust valve springs, and is easier to locate than the cylinder assembly P/N.

(4) Note that the set of numbers appearing on the cylinder, above and to the left of the SN, in the form of "123456" is not used for determining applicability.

Unsafe Condition

(d) This AD results from reports of 45 failures with head separations of ECi cylinder assemblies. We are issuing this AD to prevent loss of engine power due to cracks at the head-to-barrel interface in the cylinder assemblies and possible engine failure caused by separation of a cylinder head, which could result in loss of control of the aircraft.

Compliance

(e) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.

Engines Not Overhauled or Cylinder Assemblies Not Replaced Since New

(f) If your engine has not been overhauled or had any cylinder assemblies replaced since new, no further action is required.

Engines Overhauled or Cylinder Assemblies Replaced Since New

(g) If your engine was overhauled or had a cylinder assembly replaced since new, do the following:

(1) Before further flight, inspect the maintenance records and engine logbook to determine if the overhaul or repair facility used ECi cylinder assemblies, P/N AEL65102, with cylinder head, PN AEL85099, with a SN 1138-02 through SN 35171-22, or a SN 35239-01 through SN 37016-28, installed.

(2) If the cylinder assemblies are not ECi, P/N AEL65102, no further action is required.

(3) If the cylinder assemblies are ECi, P/N AEL65102, and if the serial number is not listed in this AD, no further action is required.

(4) If the cylinder assemblies are ECi, P/N AEL65102, and if the serial number is listed in this AD, do the following:

Group "A" Cylinder Assemblies

(i) For Group "A" cylinder assemblies:

(A) Perform an initial visual inspection as specified in paragraphs (h) through (j) of this AD, and an initial compression test as specified in paragraphs (k) through (o) of this AD, within the next 10 operating hours time-in-service (TIS), if the cylinder assembly has 350 or more operating hours TIS on the effective date of this AD, but fewer than 2,000 operating hours TIS.

(B) Perform an initial visual inspection as specified in paragraphs (h) through (j) of this AD, and an initial compression test as specified in paragraphs (k) through (o) of this AD, before exceeding 350 operating hours TIS, if the cylinder assembly has fewer than 350 operating hours TIS on the effective date of this AD.

(C) Replace cylinder assemblies installed in helicopter engines within the next 25 operating hours TIS after the effective date of this AD if the cylinder assembly has 1,500 operating hours TIS or more on the effective date of this AD.

(D) Replace cylinder assemblies installed in airplane engines within the next 25 operating hours TIS after the effective date of this AD if the cylinder assembly has 2,000 operating hours TIS or more on the effective date of this AD.

(E) Perform repetitive visual inspections as specified in paragraphs (h) through (j) of this AD, and repetitive compression tests as specified in paragraphs (k) through (o) of this AD, within every 50 operating hours TIS.

(F) Replace cylinder assemblies installed in helicopter engines that pass the visual inspections and compression tests, no later than 1,500 operating hours TIS after the effective date of this AD.

(G) Replace cylinder assemblies installed in airplane engines that pass the visual inspections and compression tests, no later than 2,000 operating hours TIS after the effective date of this AD.

Group "B" Cylinder Assemblies

(ii) For Group "B" cylinder assemblies:

(A) Perform an initial visual inspection as specified in paragraphs (h) through (j) of this AD, and initial compression test as specified in paragraphs (k) through (o) of this AD, within an additional 10 operating hours TIS.

(B) Replace the cylinder assembly within the next 25 operating hours TIS after the effective date of this AD if the cylinder assembly has 350 or more operating hours TIS on the effective date of this AD.

(C) Replace cylinder assemblies that pass the initial visual inspections and compression tests, before exceeding 350 operating hours TIS after the effective date of this AD.

Visual Inspection

(h) Visually inspect around the exhaust valve side, for cracks or any signs of black or white residue of combustion leakage from cracks.

(i) Replace cracked cylinder assemblies before further flight.

(j) Information on cylinder assembly visual inspection can be found in ECi Mandatory Service Bulletin (MSB) No. 08-1, Revision 3, dated August 19, 2008.

Cylinder Assembly Compression Test

(k) Compression test the cylinder assembly.

(l) Information on cylinder assembly compression testing can be found in ECi MSB No. 08-1, Revision 3, dated August 19, 2008.

(m) During the compression test, if the cylinder pressure gauge reads below 70 pounds-per-square-inch, apply a water and

[Page Number 53113]

soap solution to the side of the leaking cylinder, near the head-to-barrel interface.

(n) Replace the cylinder assembly before further flight, if air leakage and bubbles are observed on the side of the cylinder assembly, near the head-to- barrel interface.

(o) Repair or replace the engine cylinder assembly before further flight if the cause of the low gauge reading in paragraph (m) of this AD is from leaking intake or exhaust valves, or from leaking piston rings.

Prohibition of ECi Cylinder Assemblies Affected by This AD

(p) After the effective date of this AD, do not install any ECi cylinder assembly, P/N AEL65102, with cylinder head, P/N AEL85099, and with SN 1138-02 through SN 35171-22, or SN 35239-01 through SN 37016-28, onto any engine, and do not attempt to repair or reuse these ECi cylinder assemblies.

Alternative Methods of Compliance

(q) The Manager, Special Certification Office, has the authority to approve alternative methods of compliance for this AD if requested using the procedures found in 14 CFR 39.19.

Special Flight Permits

(r) Under 14 CFR 39.23, we will not approve special flight permits for this AD for engines that have failed the visual inspection or the cylinder assembly compression test required by this AD.

Rules and Regulations

Market sources said that the venture will cease production of the aforesaid two Chrysler models soon and the saying was thought to be closely related to the interest distribution issue between the US carmaker and its venture.

After departing with Daimler, Chrysler quitted the Beijing-based venture but its two car models would still be made there. So the two parties started negotiation on the contractual production of the two cars. Chrysler also needs to pay marketing fees to the venture because it sells the cars via the latter's sales network.

From www.cnstock.com, Page 1, Friday, September 12, 2008
 info@SinoCast.Com

After the split of Daimler and Chrysler, Beijing Benz and Chrysler had disputes over utilization fees of authorized models and promotion costs for Chrysler's products.

Chrysler expressed that it will cooperate with Beijing Benz to ensure the successful launch of Chrysler 300C and Sebring cars in Chinese market.

Chrysler's sales volume will increase more than 100 per cent in China this year.
