Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, -700, and -800 series airplanes. This action requires installation of placards on the P3-1 panel. This action is necessary to prevent loss of communication between the flight crew and Air Traffic Control; this situation could result in the flight crew being unaware of an unsafe scenario when the airplane is on the ground. This action is intended to address the identified unsafe condition.
To prevent loss of communication between the flight crew and Air Traffic Control (ATC), which could result in the flight crew being unaware of an unsafe scenario when the airplane is on the ground, accomplish the following:
(a) Within 60 days after the effective date of this AD, install placards on the P3-1 panel in accordance with Boeing Alert Service Bulletin 737-23A1170, dated April 27, 2000.
