We propose to revise airworthiness directive (AD) 99-26-19 that applies to certain The New Piper Aircraft, Inc. Model J-2 airplanes equipped with wing lift struts. AD 99-26-19 currently requires repetitively inspecting the wing lift struts for dents and corrosion; repetitively inspecting the wing lift strut forks for cracks; replacing any dented or corroded wing lift strut; replacing any cracked wing lift strut fork; and repetitively replacing the wing lift strut forks at specified times for certain airplanes. AD 99-26-19 also currently requires incorporating a ``NO STEP'' placard on the wing lift strut. Since we issued AD 99-26-19, we have been informed that paragraph (c) is being misinterpreted and causing confusion. This proposed AD would clarify the intent of the language currently in paragraph (c) of AD 99-26-19 and would retain all other requirements of AD 99-26-19. We are proposing this AD to correct the unsafe condition on these products.
