The National Civil Aviation Administration’s (ANAC) General Aviation Department (DAG) issued a warning about the procedures that maintenance depot should consider for the inspection of the landing gear selector valve in general aviation aircraft.
This was a response to Safety Recommendation (SR) Nº 1525 included in the Safety Report of the accident of aircraft Cessna 201 registration LV-OCP, on 15 April 2015, in San Fernando Airport (Buenos Aires)
In compliance with what that department informed, after conducting a data collection inspection on the crashed aircraft, “they learned that the component that triggered the accident had been the gear selector valve.”
The official note emphasizes that “they performed an audit of the Maintenance Records of TAR 1B-30, without any new developments that demonstrate failures in the Quality Control System.” However, they issued warning N°176/DAG recommending cares and verifications to take into account during work on the landing gear selector valve.
JIAAC safety recommendation urged ANAC to “carry out, as soon as possible, an inspection of the Depot – Approved Maintenance Organization (OMA) involved in this accident,” in order to verify that it has carried out the “recommended wide scope and in-depth changes” and that it “has taken all necessary measures and changes” to “ensure that inspection procedures or maintenance controls are carried out in accordance with prevailing and established standards of control and quality assurance.”
JIAAC considers that issuance of warning N° 176/DAG is sufficient to mitigate the risk of quality control failures.
