No judgment structure available for this case.

AIRWORTHINESS DIRECTIVE

For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.001(1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

AD/LYC/119

ECi Cylinder Assemblies

12/2008 DM

Applicability:

Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, ''Parallel Valve'', reciprocating engines listed in Table 1 of this AD, with Engine Components, Inc (ECi) cylinder assembly, part number (P/N) AEL65102 series “Titan”, and with cylinder head, P/N AEL85099, with the following serial numbers (S/N) installed.

a. Cylinder assembly S/N 1138-02 through SN 35171- 22, (referred to in this AD as Group ''A'' cylinder assemblies); and

b. S/N 35239-01 through SN 37016-28 (referred to in this AD as Group ''B'' cylinder assemblies).

Note 1: 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 the cylinder head, near the intake and exhaust valve springs, and is easier to locate than the cylinder assembly P/N.

Note 2: 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.

This AD is not applicable to engines not overhauled or which have not had any cylinder assemblies replaced since new.

Requirement:

1. If the engine was overhauled or had a cylinder assembly replaced since new, do the following:

a) 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, P/N AEL85099, with a S/N 1138-02 through SN
35171-22, or a S/N 35239-01 through S/N 37016-28, installed.

b) If the cylinder assemblies are not ECi, P/N AEL65102, no further action is required by this AD.

c) If the cylinder assemblies are ECi, P/N AEL65102, and if the S/N is not listed in this AD, no further action is required by this AD.

d) If the cylinder assemblies are ECi, P/N AEL65102, and if the S/N is listed in this AD, proceed to Requirement 2 or 3 as is applicable.

Note 3: The classification of cylinders, into Group “A” or Group “B” is detailed in the applicability section of this AD. The classification will determine whether Requirement 2 or 3 applies.

2. Group “A” Cylinder Assemblies

a) Perform an initial visual inspection as specified in Requirement 4 of this AD of this AD, and an initial compression test as specified in Requirement 5 of this AD.

b) Replace cylinder assemblies on:

Engines installed in a helicopter, if the cylinder assembly has 1,500 operating hours Time In Service (TIS) or more on the effective date of this AD; and

Engines installed in an aeroplane if the cylinder assembly has 2,000 operating hours TIS or more on the effective date of this AD.

c) Perform repetitive visual inspections as specified in Requirement 4 of this AD, and repetitive compression tests as specified in Requirement 5 of this AD.

d) Replace cylinder assemblies that pass the repetitive visual inspection and compression tests before exceeding:

1,500 hours TIS if the engine is installed in a helicopter; or

2,000 hours TIS if the engine is installed in an aeroplane.

3. Group “B” Cylinder Assemblies

a) Perform an initial visual inspection as specified in Requirement 4 of this AD, and initial compression test as specified in Requirement 5 of this AD.

b) Replace cylinder assemblies that have more than 350 hours TIS on the effective date of this AD.

c) Replace cylinder assemblies that pass the visual inspection and compression tests before exceeding 350 hours TIS.

4. Visual Inspection

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

b) Replace cracked cylinder assemblies.

Note 4: Information on cylinder assembly visual inspection can be found in ECi Mandatory Service Bulletin (MSB) No. 08-1, Revision 3, dated August 19, 2008.

5. Cylinder Assembly Compression Test

a) Compression test the cylinder assembly.

b) During the compression test, if the cylinder pressure gauge reads below 70 pounds-per-square-inch, apply a water and soap solution to the side of the leaking cylinder, near the head-to- barrel interface.

c) Replace the cylinder assembly, if air leakage and bubbles are observed on the side of the cylinder assembly, near the head-to-barrel interface.

d) Repair or replace the engine cylinder assembly if the cause of the low gauge reading in Requirement 5b of this AD is from leaking intake or exhaust valves, or from leaking piston rings.

Note 5: Information on cylinder assembly compression testing can be found in ECi MSB No. 08-1, Revision 3, dated August 19, 2008.

6. 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.

Note 6: FAA AD 2008-19-05 Amdt 39-15672 dated 5 September 2008 refers.

Compliance:

For Requirement 1 - Before further flight after the effective date of this AD.

For Requirement 2a - If the cylinder assembly has 350 or more operating hours TIS on the effective date of this AD, but fewer than 2000 hours TIS on the effective date of this AD - Within 10 hours TIS; or

If the cylinder has fewer than 350 hours TIS on the effective date of this AD - Before exceeding 350 hours TIS.

For Requirement 2b - Within the next 25 operating hours TIS after the effective date of this AD.

For Requirement 2c - Within every 50 operating hours TIS.

For Requirement 2d - After the effective date of this AD.

For Requirement 3a - Within an additional 10 operating hours TIS after the effective date of this AD.

For Requirement 3b - Within the next 25 operating hours TIS after the effective date of this AD.

For Requirement 3c - After the effective date of this AD.

For Requirement 4b - Before further flight.

For Requirements 5c and 5d - Before further flight.

For Requirement 6 - After the effective date of this AD.

This Airworthiness Directive becomes effective on 20 October 2008.

Background:

This AD requires 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. 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.
