Plain English Summary

2/10 complexity

This directive mandates a specified modification/rework of the passenger and service door mechanism on certain BAe 146 series aeroplanes (per BAe Mandatory SB 52-89-00668 revisions) because a high outward door force can prevent the side baulk blade from retracting and impede evacuation.

It affects operators and maintenance organisations, requires completion by 31 October 1991, corrects a previous dimension error in the earlier fix, and costs (parts, labour, downtime) are borne by operators.

Amdt 1

Passenger and Service Door Mechanism 9/91

Applicability: Models & Constructors numbers; as specified in BAe 146 SB 52-89-00668H, J, K & L Revision 2.

Requirement: Action in accordance with BAe Mandatory SB 52-89-00668H, J, K & L Revision 2. Compliance: Prior to 31 October 1991.

Background: Constant high outward force on the door during opening sequence may prevent the side baulk blade from retracting, this hindering emergency evacuation. Modifications required by the initial issue of this Directive introduced stronger springs to increase tension at the side baulk blade.

This amendment requires additional work for aircraft already modified, due to a dimension error. Compliance date required by the UK CAA is extended by three months.
