EASA AD BR-2018-07-01R2
Landing Gear - Pintle Pins of the Main Landing Gear Shock Struts - Inspection
Summary
Brazilian Airworthiness Directive AD No. 2018-07-01R2 mandates inspection of the Pintle Pins on the Main Landing Gear Shock Struts for Embraer S.A. ERJ 190-100 and ERJ 190-200 series airplanes. This directive addresses corrosion and chromium layer chipping issues on the forward and rearward Pintle Pins that could lead to landing gear collapse during takeoff or landing. The AD requires detailed inspections and corrective actions as specified in Embraer Service Bulletin Nº 190-32-0065, revision 05.
What Changed
This AD revises a paragraph related to compliance timing and cancels and supersedes the previous AD No. 2018-07-01R1. It updates inspection intervals and clarifies inspection requirements for Pintle Pins with specific part numbers and flight cycle thresholds. The directive also incorporates the latest revision of the Embraer Service Bulletin for inspection procedures.
Why It Matters
This directive is critical for maintaining flight safety by preventing potential failure of the Main Landing Gear due to Pintle Pin corrosion or damage. Operators and maintenance organizations must ensure timely inspections and repairs to avoid gear collapse during critical phases of flight. Compliance helps avoid unplanned maintenance and operational disruptions caused by landing gear failures.
What To Do
Operators must perform detailed inspections of the forward and rearward Pintle Pins on both main landing gear shock struts following Embraer Service Bulletin Nº 190-32-0065, revision 05. Inspections must be completed before Pintle Pins reach specified flight cycle limits or within 750 flight cycles if already beyond the threshold as of July 24, 2018. Any discrepancies found require corrective action before further flight, with repeat inspections every 72 months after installation.
