AD 95-03-10 Push Rod Inspection
January 24, 1996
This AD applies to all Lycoming 0-235 engines shipped from the factory between Feb 93 and Sep 94, and others that may have push rods with part number 73806.
This AD required a one-time inspection to determine the part number (P/N) and revision letter of the push rod installed on the engine. All push rods with P/N 73806 and revision letters “V” or “W” must be replaced with serviceable parts. This AD was prompted by reports of several failures of these push rods. The actions specified by this AD are intended to prevent engine roughness and power loss, which could result in loss of the aircraft.
95-03-10 Textron Lycoming: Amendment 39-9458. Docket 94-ANE-63.
Applicability: Textron Lycoming O-235 series reciprocating engines, shipped from the factory between February 22, 1993, and September 2, 1994, and identified by serial number in Textron Lycoming Mandatory Service Bulletin (MSB) No. 522, dated November 1, 1994; and all Textron Lycoming O-235 series reciprocating engines that have had push rods, part number (P/N) 73806, installed as service parts on or after February 22, 1993.
These engines are installed on but not limited to the following aircraft: Piper PA-11, -12, -18, -22, -28, -38; Cessna 152, A152; Beech 77; Taylorcraft F-21; and Gulfstream American AA1 series aircraft.
NOTE 1: This airworthiness directive (AD) applies to each engine identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For engines that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must use the authority provided in paragraph (b) to request approval from the Federal Aviation Administration (FAA). This approval may address either no action, if the current configuration eliminates the unsafe condition, or different actions necessary to address the unsafe condition described in this AD. Such a request should include an assessment of the effect of the changed configuration on the unsafe condition addressed by this AD. In no case does the presence of any modification, alteration, or repair remove any engine from the applicability of this AD. NOTE 2: This amendment does not supersede AD 80-25-02 R2, which also applies to pushrod P/N 73806. AD 80-25-02 R2 continues in effect and must be complied with.
Compliance: Required as indicated, unless accomplished previously.
To prevent engine roughness and power loss, which could result in loss of the aircraft, accomplish the following:
(a) Within 5 hours time in service (TIS) after the effective date of this AD, inspect push rods for P/N and revision letter. All push rods with P/N 73806 and revision letter “V” or “W” must be replaced with serviceable parts in accordance with Textron Lycoming MSB No. 522, dated November 1, 1994.
(b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, New York Aircraft Certification Office. The request should be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, New York Aircraft Certification Office. NOTE: Information concerning the existence of approved alternative methods of compliance with this airworthiness directive, if any, may be obtained from the New York Aircraft Certification Office.
(c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the aircraft to a location where the inspection required by this AD can be accomplished.
(d) The actions required by this AD shall be done in accordance with the following MSB:
