AD: Rockwell Collins, Inc. Transponders

AD NUMBER: 2014-18-01

PRODUCT: Certain Rockwell Collins TDR-94 and TDR-94D Mode select (S) transponders that are installed on airplanes.

ACTION: Final Rule

SUMMARY:  This AD was prompted by instances where the TDR-94 and TDR-94D Mode S transponders did not properly respond to Mode S Only All-Call interrogations when the airplane transitioned from a ground to airborne state.

This AD requires inspecting the setting of the airplane type code category strapping and requires either modifying the airplane type code category setting or installing the software upgrade to convert the affected transponders to the new part number.

The FAA is issuing this AD to correct the unsafe condition on these products.

DATES: This AD is effective October 14, 2014.
