The design change effected by this Aircraft Service Change (ASC) has been classified as Major/Not Significant by the United States Federal Aviation Administration (FAA) and Level 2 Major/Not Significant by the European Aviation Safety Agency (EASA). The design change data contained in this document is approved and accepted by the FAA and EASA under Gulfstream Organization Delegation Authorization (ODA) project number:

FAA / EASA – Project Number TD-01-2011-0017

The design of this ASC is approved by aircraft type design data for installation on aircraft registered for operation in accordance with applicable regulations of the FAA and EASA.

The design of an ASC is configured to a standard (“green”) production aircraft. If spare wires, pin connections or locations called out have been used for another modification, the installing agency must ensure the development, documentation and approval of any required deviations.

The following instructions, in step-by-step form, are written as a guide to perform this ASC. Compliance with safe maintenance practices, as defined in the Aircraft Maintenance Manual and FAA or EASA regulations, is required. It is the responsibility of the installing facility to read all instructions contained in this service change and refer to all associated documents, drawings and manuals for applicable actions.

Gulfstream considers this ASC a means to enhance aircraft capabilities to meet individual operator requirements. The modification is not related to any safety or airworthiness condition.

Subject: Indicating / Recording (ATA 31) – PlaneView Master Operating System Software Update

Purpose / Discussion: This service change installs new PlaneView Master Operating System (MOS) software on G450 aircraft. This service change enhances the overall performance and reliability of the PlaneView Avionics System.

This revision addresses an issue discovered with the Static Source Error Correction (SSEC) on aircraft having the newer Goodrich AOA vanes installed. Goodrich AOA vanes are installed from production, or by incorporation of ASC 055, and are the preferred spare and replacement.

During take-off, false miscompares have been displayed prior to the AOA vanes stabilizing at 80 knots indicated air speed resulting in rejected take-offs (RTOs). This software update includes changes to the SSEC algorithm called the “washout filter”. This “washout filter” was implemented to maintain stable and accurate indications of airspeed and altitude during high alpha maneuvers, especially during takeoff rotation. Incorporation of MOS, PN EB7031236-00415 resolves these issues.

Purpose / Discussion continued: Several operators have also reported low fuel tank temperature indications while flying missions within the approved flight envelope. As a result, the low fuel tank temperature indication limits have been adjusted to address the nuisance caution and warning indications.

This revision provides additional authorities to allow installation on aircraft operating under EASA/JAA regulations.

Description / Man-Hours Required Per Aircraft:

This service change updates the MOS with PN EB7031236-00415. This ASC must be installed in conjunction with ASC 058C. Approximately 10 man-hours will be required for this installation.

Aircraft having any previous version of ASC 908 must comply with ASC 908C. Aircraft having complied with ASC 908B have met the intent of this revision and should return the service reply card marked “previously complied with” indicating the date of compliance.
