This page transmits Revision ‘A’ of Service Bulletin 84-32-99, pages 1 thru

20, dated 02 Oct 2012.

This service bulletin is re-issued in its entirety for the reasons that follow:

- the References section is revised to convey the latest revision of the service

bulletin and engineering documentation

- the Parts Required Per Aircraft section is revised to delete material Part

Number 05-01 and to add material Part Number 05-27

- Step (6)(c) in Procedure section of ACCOMPLISHMENT INSTRUCTIONS

part is revised as follows:

- changed adhesive, was EC 1300 now EC 1300L

- changed manual reference, was AMM, PSM 1-84-3, Chapter 51-22-10

now SRM, PSM 1-84-3, Chapter 51-22-15.

SUBJECT: Landing Gear, RH Nacelle, Parking Brake Hand Pump Lever

Relocation from Nacelle to Nose Compartment - ModSum 4-113723

1. PLANNING INFORMATION

A. Effectivity

Aircraft Affected:

In-Service: DHC-8 Aircraft Models 401 and 402 Serial Numbers 4001,

4003 thru 4419

Revision ‘A’ 02 Oct 2012

Spares Affected:

None

B. Reason

Problem: An operator had reported an incident which involved the migration of the

main landing gear parking brake hand pump lever resulting in the damage

of the nacelle side panels.

During the incident, the parking brake pump lever located in the RH nacelle

had dislodged from its mounting bracket and migrated down from the

upper retaining collar and fell over inside the nacelle.

Due to the unpredictable nature of an object migrating from its mounting

position, the possibility exists that the pump lever could lodge itself into a

position that would prevent the extension of the MLG or prevent the nacelle

doors from opening or become runway F.O.D.

Cause: The quick release pin used to secure the pump lever installation may not

have been correctly installed, compromising the installation. If the quick

release pin is not fully engaged, the potential exists for the pin to migrate

out, disengaging, and allowing the pump lever to become dislodged from

its installation position.

Solution: ModSum 4-113723 relocates existing parking brake hand pump lever from

RH nacelle to the flight deck web in the RH nose compartment.

C. Description

The procedures in this service bulletin give the instructions to do the tasks that

follow:

- aircraft is put into standard configuration for maintenance

- aircraft electrical power is removed

- the nose landing gear lock is engaged

- the main landing gear lock pins are installed through each main gear and main gear

door mechanism
