Nav-Aids APA97634HT-3-4-4 - Smart Probe Adaptor Hawk 128

The Nav-Aids APA97634HT-3-4-4 is an alpha probe test adaptor engineered for the SMART probes on the BAE Systems Hawk 128 military jet trainer. Manufactured by Nav-Aids Ltd. of Montreal — the industry-leading manufacturer of pitot-static test adaptors and air data accessories kits — it enables MRO technicians and military aviation maintenance professionals to isolate and test the AOA (angle of attack), pitot, and static systems on the Hawk 128 separately or simultaneously, in compliance with the Hawk 128 Aircraft Maintenance Manual. Two units are required per aircraft, one for each nose-mounted SMART probe.
