AD 2020-24-05 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 the following Piper Aircraft, Inc. model airplanes that are certificated in any category: ER23NO20.002
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within the next 100 hours time-in-service (TIS) after the effective date of this AD or within the next 12 months after the effective date of this AD, whichever occurs first, and thereafter at intervals not to exceed 7 years, inspect the forward and aft surfaces of the left and right main wing spars between wing station (WS) 24.24 and WS 49.25 for corrosion as follows. (1) Gain visual access to the inspection area by complying with either paragraph (g)(1)(i), (ii), (iii), or (iv) of this AD. Note 1 to paragraph (g)(1) of this AD: Step 1 and figure 1 in Part I Wing Spar Inspection of Piper Aircraft, Inc. Service Bulletin No. 1304A, August 14, 2018 (Piper SB No. 1304A), contain instructions you may use for identifying the inspection area and determining if wing access panels have been installed. (i) Remove existing wing inspection access panels and fairings. (ii) Install Inspection Access Hole Kit part number 765-106V, and then remove the wing inspection access panels and fairings. (iii) Access the inspection area during concurrent maintenance such as a wing tank removal, wing removal, or wing skin repair. (iv) Use a lighted borescope capable of 10X or higher power magnification display through existing access points ( e.g., wing root fairing, landing gear panels, internal lightening holes, or other access points depending on model). (2) Identify the wing spar configuration for your airplane in accordance with table 1 and figure 2 (sheets 1 and 2) in Part I Wing Spar Inspection of Piper SB No. 1304A. Visually inspect each spar component for evidence of corrosion, including irregularities such as blisters, flakes, chips, lumps, bulging skin, and missing rivets. Note 2 to paragraph (g)(2) of this AD: Paint coatings may mask the initial stages of corrosion, and faying surfaces, such as riveted lap joints, may hide corrosion.
Unsafe condition
This AD was prompted by reports of corrosion found in an area of the main wing spar not easily accessible for inspection. The FAA is issuing this AD to detect and correct corrosion in the wing root area of the left and the right main wing spars. Corrosion of the main wing spar, if not detected and corrected, could cause the main wing spar to fail with consequent loss of control of the airplane.
Affected ADs
None.
