Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and EMB-145 Series Airplanes

Resumen

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-135 and EMB-145 series airplanes. This proposal would require replacement of the engine oil pressure sensors with new sensors, and installation of an oil tank pressure relief kit. Additionally, the proposal would require revision of the Airplane Flight Manual that would specify new oil pressure limits. This action is necessary to prevent rejected takeoffs due to exceeding engine oil pressure limits, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
