EASA AD BR-1999-02-01R7
Aileron PCA Rod Ends and Fittings - Inspections
Summary
Brazilian Airworthiness Directive AD No. 1999-02-01R7 issued by ANAC addresses inspection and reinforcement requirements for aileron PCA rod ends and fittings on Embraer S.A. EMB-145 aircraft models, excluding EMB-135 models. The directive mandates repetitive visual inspections and installation of new reinforced parts to ensure structural integrity and flight safety. It includes specific part numbers for affected PCAs and fittings and references Embraer Service Bulletins for compliance procedures.
What Changed
This revision 7 of AD No. 1999-02-01 corrects the previously incorrect visual inspection task number referenced in the earlier revision 6. It replaces the task reference from AMM TASK 27-12-01-212-002-A00 to MRB-145/1150 TASK 27-12-01-212-002-A05. Additionally, an errata was issued to correct printing errors in the English version of the original AD regarding the task reference and inspection paragraph.
Why It Matters
This AD is critical for aviation professionals as it addresses recurring failures of aileron PCA rod ends and fittings that can compromise flight safety. Operators and maintenance organizations must adhere to the inspection intervals and reinforcement installations to prevent structural failures. Compliance ensures continued airworthiness of the affected Embraer EMB-145 fleet and avoids potential operational disruptions or safety incidents.
What To Do
Operators of Embraer EMB-145 aircraft must perform repetitive visual inspections of the aileron PCA rod ends and fittings at specified intervals depending on PCA part numbers. If cracks or failures are found, affected parts must be replaced with new reinforced components as detailed in the referenced Embraer Service Bulletins. Installation of new fittings and reinforcements must be completed before 6000 operating cycles, and ongoing inspections must follow the updated task MRB-145/1150 TASK 27-12-01-212-002-A05 every 500 flight hours. All actions must be recorded in maintenance logs.
