Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135ER and -135LR Series Airplanes, and Model EMB-145, -145ER, -145MR, and -145LR Series Airplanes
Superseded. A later AD replaced this one: AD 2002-08-21. Comply with the one in force.
Model EMB-135ER and -135LR series airplanes, and Model EMB-145, -145ER, -145MR, and -145LR series airplanes, as listed in EMBRAER Alert Service Bulletin 145-55-A025, dated June 5, 2001; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-135ER and -135LR series airplanes, and Model EMB-145, -145ER, -145MR, and -145LR series airplanes. This action requires a one-time visual inspection to determine if the two bonding jumpers that connect the horizontal stabilizer to the vertical stabilizer are properly installed, and replacement of the jumper with a new jumper, if necessary. This action also requires a one-time visual inspection to determine if the supports that connect the bonding jumpers to the horizontal stabilizer are deformed, and corrective actions, if necessary. This action is necessary to prevent severed bonding jumpers in the event of a lightning strike, which could result in reduced elevator control capability, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
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.
