A. EFFECTIVITY

This Service Bulletin is applicable to all FAN JET FALCON series and MYSTERE-FALCON 20-()5

Due to a manufacturing defect, some batches of charge indicators installed on fire extinguishers on Fan

Jet Falcon, Mystere-Falcon 20-()5 and Falcon 200 may be subject to corrosion and not properly indicate

a loss of pressure inside the bottle.

This could lead to a dormant failure impacting the capability to extinguish fires either in engine(s) or APU

or rear compartments.

The purpose of this Service Bulletin is to identify the batch number of the charge indicator installed on

each fire extinguisher.

C. DESCRIPTION

The operation consists in :

• checking the manufacturing batch number of the charge indicator installed on each fire

extinguisher,

• weighing the suspected ones.

D. COMPLIANCE

Mandatory:

• It is anticipated that this Service Bulletin will be rendered mandatory by an EASA Airworthiness

Directive.

• As prescribed by the Airworthiness Authorities of the country of registration of the aircraft.

E. APPROVAL

The technical content of this document is approved under the authority of DOA nr. EASA.21J.051.

F. LABOR

Estimated labor-hours:

• Identification of the batch numbers: 1 hour

• Weighing: 1h30 per fire extinguisher
