PILATUS AIRCRAFT LTD.: Amendment 39-21313; Docket No. FAA-2020-0719; Project Identifier 2019-CE-041-AD. |
(a) EFFECTIVE DATE This airworthiness directive (AD) is effective December 14, 2020. (b) AFFECTED ADS None. (c) APPLICABILITY This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, all serial numbers, certificated in any category, with a flexible saddle clamp part number (P/N) 946.33.22.004 installed between frame 34 and 36. (d) SUBJECT Joint Aircraft System Component (JASC) Code 2800: Fuel. (e) REASON This AD was prompted by an occurrence of movement of the aft fuel pipe within the coupling when system pressure was applied. This movement can cause damage to the O-rings, which could lead to a fuel leak and fuel contamination of the rear fuselage. The FAA is issuing this AD to prevent a fuel fire or fuel vapor explosion with consequent loss of airplane control. (f) ACTIONS AND COMPLIANCE Unless already done, do the following actions in accordance with the applicable compliance times: (1) Within 3 months after the effective date of this AD, replace each flexible saddle clamp with a fixed saddle clamp with P/N 946.33.21.933, align the left-hand (LH) and right-hand (RH) motive -flow fuel pipes, and test the LH and RH motive-flow fuel pipe for leaks in accordance with the Accomplishment Instructions, sections 3.B and 3.C, of Pilatus PC-24 Service Bulletin No. 28-002, dated May 3, 2019.
