## Abstract

We are revising 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 required 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 required incorporating a "NO STEP" placard on the wing lift strut. Since we issued AD 99-26- 19, we were informed that paragraph (c) had been misinterpreted and caused confusion. This AD clarifies the intent of the language in paragraph (c) of AD 99-26-19 and retains all other requirements of AD 99-26-19. We are issuing this AD to correct the unsafe condition on these products.
