Plain English Summary

3/10 complexity

This AD requires operators of Boeing 737‑100 and 737‑200 aircraft (which currently use only right main‑gear oleo compression) to install an approved modification so the Air/Ground Sensing System also uses nose‑gear strut compression to enable thrust reversers. Compliance is mandatory within 30 days of the AD (effective 19 January 2006).

The stated purpose is to ensure timely reverse‑thrust deployment on landing in adverse weather or runway conditions. The cost and installation burden fall to operators, who must obtain an approved modification and schedule work in the short compliance window.

AD/B737/272	Thrust Reverser Ground Logic	1/2006

Applicability:	Boeing Model 737-100 and 737-200 series airplanes, which presently do not use nose gear compression logic to enable thrust reversers.
Requirement:	Install an approved modification to the Air/Ground Sensing System which causes the thrust reverser logic to be enabled by nose gear strut compression in addition to the present logic of the right main gear oleo compression.Note: FAA AD 89-08-08 Amdt 39-6191 refers.
Compliance:	Within 30 days after the effective date of this AD.
	This Airworthiness Directive becomes effective on 19 January 2006.
Background:	The requirements of this AD are to ensure timely deployment of reverse thrust when landing under adverse weather and runway conditions.
