PIPER AIRCRAFT, INC.:
Amendment 39-21339; Docket No. FAA-2020-0712; Product Identifier 2019-CE-013-AD.
(a) EFFECTIVE DATE This airworthiness directive (AD) is effective January 5, 2021. (b) AFFECTED ADS None. (c) APPLICABILITY This AD applies to Piper Aircraft, Inc., Model PA-34-220T airplanes, serial numbers 3449459 and 3449467 through 3449508, certificated in any category. (d) SUBJECT Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 27. Flight Controls. (e) UNSAFE CONDITION This AD was prompted by a report of damage to the rudder flight control cables and the emergency power supply (EPS) system wiring due to inadequate clearance from the EPS wiring harness. The FAA is issuing this AD to detect, correct, and prevent damaged rudder flight control cables and EPS system wiring. The unsafe condition, if not addressed, could result in electrical arcing between the EPS and the rudder flight control cables with consequent failure of the rudder flight control system. This failure could cause loss of yaw control and lead to loss of control of the airplane during an engine out condition/operation. (f) COMPLIANCE Unless already done, comply with this AD within 50 hours time-in- service after the effective date of this AD or within 6 months after the effective date of this AD, whichever occurs first. (g) INSPECT, REPLACE, AND RELOCATE (1) Inspect the rudder flight control cables and the EPS wiring for chaf- ing and damage by following step 3 of the Instructions in Piper Service Bulletin No. 1337, dated February 15, 2019 (Piper SB No. 1337). If there is any chafing or damage, before further flight, replace the rudder flight control cable and EPS wiring. (2) Relocate the EPS wiring harness by following steps 4 through 12 of the Instructions in Piper SB No. 1337. (h) ALTERNATIVE METHODS OF COMPLIANCE (AMOCS) (1) The Manager, Atlanta ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (i) of this AD. (2) Before using any approved AMOC, notify your appropriate principal in- spector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. (3) For service information that contains steps that are labeled as Re- quired for Compliance (RC), the following provisions apply. (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. An AMOC is required for any deviations to RC steps, including substeps and identified figures. (ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.
