SUBJECT: Airworthiness Directive 2007-25-05
SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority ofanother country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: SUMMARY: We are adopting a new airworthiness directive(AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct anunsafe condition on an aviation product. The MCAI describes the unsafe condition as: It has been discovered that a batch of sleeves and pins of the Rolls-Royce Trent 700 Thrust Reverser Unit(TRU) hinge n° [number] 5 has not been subjected to the correct precipitation hardening. This production quality issue, if not corrected, can lead to the complete failure of the hinge n° 5-theremaining hinges may not sustain ultimate load-resulting in the worst case to the TRU release from the pylon, which constitutes an unsafe condition. The degradation of the mechanical specifications of these parts puts into question the current design life goal of these parts. * * * The unsafe condition is possible detachment of the thrust reverser unit from the airplane, which could result in reduced controllability and possible damage to the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
