AD NUMBER: 99-01-05 R1

PRODUCT: Certain aircraft equipped with wing lift struts
SUBJECT: Airworthiness Directive 99-01-05 R1
ACTION: Final Rule

SUMMARY: The FAA is revising Airworthiness Directive (AD) 99-01-05 for certain aircraft equipped with wing lift struts.

AD 99-01-05 required repetitively inspecting the wing lift struts for corrosion; repetitively inspecting the wing lift strut forks for cracks; replacing any corroded wing lift strut; replacing any cracked wing lift strut fork; and repetitively replacing the wing lift strut forks at a specified time for certain airplanes. AD 99-01-05 also required incorporating a "NO STEP" placard on the wing lift strut.

Since AD 99-01-05 was issued, the FAA was informed that paragraph (c) had been misinterpreted and caused confusion. This AD clarifies the intent of the language in paragraph (c) of AD 99-01-05 and retains all other requirements of AD 99-01-05. The FAA is issuing this AD to correct the unsafe condition on these products.

DATES: This AD is effective January 14, 2014.
