1. PLANNING INFORMATION

A. EFFECTIVITY

This Service Bulletin is applicable to MYSTERE-FALCON 50 aircraft with serial numbers 5, 7, 27, 30,

34, 36, 78, 132, 251 through 352 and aircraft with DASSAULT AVIATION Service Bulletin F50-280

"Installation of ALLIED SIGNAL TFE731-40-1C engines".

B. REASON

Following an incident on in-service aircraft where the green slat extended light was permanently

illuminated, investigations have shown that the wire bundle located behind the warning panel rubbed

against the engine 3 fire "T" handle lock cap leading to wire cut and smoke in cockpit.

Depending on the wire affected, several effects might occur:

• untimely indication of reverser unlocking,

• untimely indication of either slat or flap or airbrake or arthur active,

• possible short-circuit of one 80 Amp-rated feeder supplying the pilot windshield de-icing system,

• possible activation of audio silencer in the audio warning unit for a few warnings, however the

associated visual warnings remain unaffected,

• possible malfunction of RH display,

• possible malfunction of integrated avionics processor system power supply.

The purpose of this Service bulletin is to prevent the chafing under the glareshield and behind the

warning panel by adding protective plates to the wire bundles.

C. DESCRIPTION

This operation consists in adding two Rilsan protective plates between the glareshield electrical wiring

and the engine fire pull handles.

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

Directive.
