Airworthiness Directive · Amendment 39-10536 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 Series Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 Series Airplanes
Model EMB-145 series airplanes; as listed in EMBRAER Service Bulletin 145-28-0005, dated May 23, 1997, and EMBRAER Service Bulletin 145-28-0006, dated October 22, 1997; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-145 series airplanes, that requires a one-time visual inspection of the pilot valve harness tubes for bulges and cracks, cleaning the tubes, applying sealant at the tube end opening, and replacing any discrepant tubes with serviceable tubes. This amendment also requires replacement of the pilot valve harness tubes and vent valve tubes with new tubes having improved anti- corrosion protection. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent cracking of the pilot valve harness tubes, which could allow fuel to enter the conduit and leak overboard; this condition could result in increased risk of a fuel tank explosion and fire.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
