[Docket No. 2004-NE-07-AD; Amendment 39-13579; AD 2004-08-10]
RIN 2120-AA64


Airworthiness Directives; Engine Components Incorporated (ECi) 
Reciprocating Engine Cylinders

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Teledyne Continental Motors (TCM) models 520 and 550 series engines 
with certain ECi cylinders installed. This AD requires replacing 
certain serial-numbered (SN) cylinders supplied by ECi before further 
flight. This AD results from reports of 34 failures of cylinder heads 
marketed by ECi. We are issuing this AD to prevent loss of engine power 
due to cracks in the cylinder head and possible engine failure caused 
by separation of a cylinder head.

DATES: This AD becomes effective May 5, 2004.
    We must receive any comments on this AD by June 21, 2004.

ADDRESSES: Use one of the following addresses to submit comments on 
this AD:

Certification Office, FAA, Rotorcraft Directorate, 2601 Meacham Blvd., 
Fort Worth, TX 76193; telephone (817) 222-5199; fax (817) 222-5785.

SUPPLEMENTARY INFORMATION: On February 1, 2003, we received a report of 
an ECi cylinder head, part number (P/N) AEC65385, that separated from 
the barrel at the head-to-barrel junction. Since that report, we have 
received reports of 27 additional ECi cylinder heads that had the same 
condition. We also received reports of six cylinder heads that had a 
crack between the 9th and 10th head fin from the head-to-barrel 
junction. All of the reported separations and cracks were located 
between the ninth and tenth head fin from the head-to-barrel junction. 
All of the cracks started on the exhaust side of the head. The ECi 
cylinder head, P/N AEC65385, is part of ECi cylinder, P/N AEC631397. 
RAM Series III, IV, and VII reciprocating engines are the primary users 
of these cylinders. The RAM series engines are TCM TSIO-520-NB, -VB, 
and -WB engines that are modified by supplemental type certificate 
(STC) SE4327SW, STC SE09104SC, or STC SE09261SC for operation at 325 HP 
or greater. In addition, we approved the engine cylinders, ECi P/N 
AEC631397 for use on TCM models 520 and 550 series reciprocating 
engines under a Parts Manufacturer Approval (PMA). The Airmotive Engine 
Division of ECi holds the PMA. ECi markets the parts as ECi parts.

Results of Manufacturer's Investigation

    An investigation by ECi revealed that cylinder heads, P/N AEC65385, 
manufactured between September 1, 2002, and May 12, 2003, SNs 1044 
through 7708, are susceptible to an over-hardened condition, which 
reduces the fatigue strength of the cylinder. It also increases the 
chance that the cylinder will crack.

Relevant Service Information

    We reviewed and approved the technical contents of RAM Aircraft 
Mandatory Service Bulletin (MSB) MSB2003-02, dated August 8, 2003, and 
ECi MSB S.I. No. 04-1, Revision 1, dated March 11, 2004, that describe 
procedures for identifying, inspecting, and replacing affected 
cylinders.

Differences Between This AD and the Service Information

    RAM Aircraft MSB MSB2003-02, dated August 8, 2003, requires 
replacing only the No. 6 cylinder, ECi P/N AEC631397, on RAM Series 
III, IV, and VII engines. ECi MSB S.I. No. 04-1, Revision 1, dated 
March 11, 2004, requires identifying the suspect cylinders on TCM 
models 520 and 550 engines and inspecting them for cracks. This AD 
requires replacing all cylinders, ECi P/N AEC631397, on all RAM Series 
III, IV, and VII engines; a\nd all TCM model 520, and 550 series 
engines.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other RAM Series III, IV, and VII engines; and TCM model 
520, and 550 series engines of the same type design. We are issuing 
this AD to prevent loss of engine power due to cracks in the cylinder 
head and possible engine failure caused by separation of a cylinder 
head. This AD requires:
     Performing a check to identify cylinders, ECi P/
N AEC631397, S/Ns 1044 through 7708, within 50 hours time-in-service 
after the effective date of this AD. and
     If a cylinder has an affected P/N and SN, 
replacing the cylinder before further flight if it was not inspected at 
ECi.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause exists for making this amendment effective in less than 30 days.

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 the regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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 by 
sending a request to us at the address listed under ADDRESSES. Include 
``AD Docket No. 2004-NE-07-AD'' in your request.

Unsafe Condition

    (d) This AD results from reports of 34 failures of ECi cylinder 
head. We are issuing this AD to prevent loss of engine power due to 
cracks in the cylinder head and possible engine failure caused by 
separation of a cylinder head.

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.

Identifying Suspect Cylinders

    (f) Within 50 hours time-in-service (TIS) after the effective 
date of this AD, identify, and if necessary replace cylinders, ECi 
P/N AEC631397 as follows:
    (1) Identify the cylinder serial number (SN) as follows:
    (i) Determine the SN of the cylinder by looking in the engine 
records or by inspecting the cylinder for a SN on the intake port 
boss (see Figure 1) or on the flat area next to the head to barrel 
junction (see Figure 2). Disregard any dash numbers that might 
follow the four digit SN.

[[Page 21052]]


[GRAPHIC] [TIFF OMITTED] TR20AP04.003

    (ii) If the SN is 1043 or lower, or if it is 7709 or higher, no 
further action is required.
    (2) If the cylinder SN is 1044 through 7708, do the following:
    (i) Remove the rocker box cover from the cylinder.
    (ii) Look at the left-front cylinder casting.
    (iii) If the casting has AEC65385, and an ``O'' under the ECi 
logo, the cylinder is P/N AEC631397. See Figure 3.
[GRAPHIC] [TIFF OMITTED] TR20AP04.004

    (iv) If the cylinder is not ECi P/N AEC631397, no further action 
is required.
    (3) If the cylinder is ECi P/N AEC631397, do the following:
    (i) Look at the flange of the rocker box.

[[Page 21053]]

    (ii) If there is a letter ``A,'' ``B,'' or ``X'' stamped on the 
flange of the rocker box, no further action is required. See Figure 
4.
[GRAPHIC] [TIFF OMITTED] TR20AP04.005

    (iii) If there is no letter ``A,'' ``B,'' or ``X'' stamped on 
the flange of the rocker box, replace the cylinder before further 
flight.

Alternative Methods of Compliance

    (g) 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.

Material Incorporated by Reference

    (h) None.
