AD 2020-26-16 Airworthiness Directives; Piper Aircraft, Inc. Airplanes
Makes named: piper. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Piper Aircraft, Inc. (Piper) airplanes, certificated in any category, with a model and serial number shown in table 1 to paragraph (c) of this AD, and that meet at least one of the criteria in paragraphs (c)(1), (2), or (3) of this AD. Note 1 to the introductory text of paragraph (c): An owner/operator with at least a private pilot certificate may do the aircraft maintenance records review to determine the applicability as specified in paragraph (c) of this AD. (1) Has accumulated 5,000 or more hours time-in-service (TIS); or (2) Has had either main wing spar replaced with a serviceable (more than zero hours TIS) main wing spar; or (3) Has missing and/or incomplete maintenance records. BILLING CODE 4910-13-P ER15JA21.014 BILLING CODE 4910-13-C
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(1) “TIS” has the same meaning as the definition of “time in service” in 14 CFR 1.1. (2) For purposes of this AD, “factored service hours” refers to the calculated quantity of hours using the formula in paragraph (h)(2) of this AD, which accounts for the usage history of the airplane.
Unsafe condition
This AD was prompted by a report of a wing separation caused by fatigue cracking in a visually inaccessible area of the main wing lower spar cap. The FAA is issuing this AD to detect and correct fatigue cracks in the lower main wing spar cap bolt holes. The unsafe condition, if not addressed, could result in the wing separating from the fuselage in flight.
Affected ADs
None.
