## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Several reports have recently been received of loose pneumatic quick-disconnect unions on Goodrich pitot probes P/N (part number) 0851HL. These may be the result of mis-torque of the affected unions at equipment manufacturing level. Investigations are still on-going to determine the root cause(s). This condition, if not corrected, could lead to an air leak, resulting in incorrect total pressure measurement and consequent erroneous Calibrated Airspeed (CAS)/MACH parameters delivered by the Air Data Computer (ADC). * * * * * Loss or fluctuation of indicated airspeed could result in misleading information provided to the flightcrew. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
