Airworthiness Directives; Pratt & Whitney Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney (PW) JT8D-217C and JT8D-219 turbofan engines. This proposed AD was prompted by reports of cracking in the low-pressure turbine (LPT) shaft. This proposed AD establishes a new lower life limit for these parts and would require removing affected LPT shafts from service using a drawdown plan. We are proposing this AD to prevent failure of the LPT shaft, which could lead to an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2009-20-05 for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2009-20-05 required one-time inspections for cracking, damage, correct installation, and correct adjustment of the main landing gear (MLG) door hinge and actuator fittings on the keel beam, and corrective actions if necessary. This new AD expands the applicability, reduces the compliance time, and requires repetitive inspections instead of the one-time inspection. This AD also requires revising the maintenance or inspection program. This AD was prompted by reports of cracks on fittings that had successfully passed certain required inspections. We are issuing this AD to detect and correct cracking on the MLG door hinge fitting and actuator fitting on the keel beam, which could lead to in-flight detachment of an MLG door, possibly resulting in injury to persons on the ground and/or damage to the airplane.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 series airplanes, Model A300 B4-600, B4-600R, and F4- 600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by a report of chafing found on the overflow sensor harness of the surge tank, and subsequent contact between the electrical wiring and fuel tank structure. This AD requires a one-time inspection for chafing of the overflow sensor harness, and repair if necessary. This AD also requires modification of the sensor harness. We are issuing this AD to prevent chafing of the harness and subsequent contact between the electrical wiring and fuel tank structure, which could result in electrical arcing and a fuel tank explosion and consequent loss of the airplane.
