AD NUMBER: 2012-26-15

PRODUCT: Certain Honeywell International Inc. air data pressure transducers as installed on various aircraft.
SUBJECT: Airworthiness Directive 2012-26-15
ACTION: Final Rule, request for comments.

SUMMARY: This AD requires various tests or checks of equipment having certain air data pressure transducers, and removal of equipment if necessary. As an option to the tests or checks, this AD allows removal of affected equipment having certain air data pressure transducers.

This AD was prompted by a report of a pressure measurement error in the pressure transducer used in various air data systems, which translates into air data parameter errors. The FAA is issuing this AD to detect and correct inaccuracies of the pressure sensors, which could result in altitude, computed airspeed, true airspeed, and Mach computation errors.

These errors could reduce the ability of the flightcrew to maintain the safe flightof the aircraft and could result in consequent loss of control of the aircraft.

DATES: This AD is effective January 24, 2013. Comments on this AD must be received by February 25, 2013.
