Airworthiness Concerns for Work Accomplished by US Aircraft Instruments SAFO 10014

This SAFO informs owners/operators of aircraft who had work done by US Aircraft Instruments between April 1998 and July 9, 2009 of potential airworthiness concerns associated with that work.
Background: Inspections done by the Federal Aviation Administration (FAA) in 2009 identified discrepancies that led to an Emergency Revocation of the Repair Station Certificate held by US Aircraft Instruments (Certificate # U3SR508J), located at 75 Academy Drive, Hammonton, NJ, 08037. The concerns that led to the revocation order involved:
• Failure to properly calibrate instruments used in aircraft certification;
• Work done outside the scope of the repair station ratings;
• Failure to use current technical data;
• Falsification of calibration records.
All of these items call into question the airworthiness of the work accomplished by US Aircraft Instruments during this time frame.
