Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-2C, B4-103, and B4-203 airplanes; Airbus Model A300 B4-600 series airplanes; and Airbus Model A300 B4-600R series airplanes. This proposed AD was prompted by reports indicating that, on airplanes that received a certain repair following crack findings, cracks can re-initiate. This proposed AD would require repetitive inspections for cracking of the frame (FR) 40 forward fittings for airplanes previously repaired. We are proposing this AD to detect and correct cracking on the FR 40 forward fittings, which could result in rupture of the forward fittings and reduction of in-flight structural strength.
