– FWD PRESSURIZED (FR “0”)

– INSPECTION / MODIFICATION

REVISION STATUS OF THE BULLETIN This Service Bulletin is at the Revision No. 3 status and consists of 24 pages. This Service Bulletin is revised to extend the effec tivity of parts A1/A2, since an aircraft previously not included in relevant effectivity, was later on identified as requiring insp ection per part A1 and subsequent reworking per part A2. As precautionary measure, effectivity of Part A1/2 is extended, including all aircraft with MSN from 1004 to 1033. Other minor and editorials change s are included in this revision. The parts which are affected by this Revision are mark ed with a vertical line on the right side of the Page. This Revision supersedes previous issues of this Service Bulletin. For airplanes MSN 1004, 1015 and 1017, compliance with Part A1/A2 of previous revisions of this Service Bulletin is adequate to show comp liance to part A1/A2 of this revision. Airplanes with MSN from 1006 to 1033 (not including MSN 1015 and 1017) are required to accomplish Part A1 (and possibly Part A2) even in compliance with part C of previous revisions of this Service Bulletin. For airplanes with MSN from 1004 to 1033, compliance with Part C of previous revisions of this Service Bulletin is adequate to show co mpliance to part C of this revision.

### B. CONCURRENT REQUIREMENTS N/A

C. REASON To restore the safe fatigue life of the airpla ne, a rework of fwd pressurized bulkhead (FR “0”) is required, as prescribed in Part C of this Service Bulletin. On some airplanes the design structural conf iguration must be rest ored, because of the absence of two reinforcements located at both end of omega-shaped beam, which is installed on fwd pressurized bulkhead. For this reason, before the embodiment of the modification required by Part C, an inspecti on, necessary to check the presence of these reinforcements, is required in accordance with Part A1, followed by their installation if these parts are missing, as prescribed in Part A2.

D. DESCRIPTION This MANDATORY Service Bulletin is divided into three Parts (A1, A2 and C) whose compliance times are differentiated. Each Part must be accomplished as follows: Part A1 – Inspection to verify “FR 0” correct configuration:

 Radome / Nosecone removal / installation.

 Visual or endoscope inspection for struct ural configuration of FR “0” (if the reinforcements are already installed, the embodiment of the subsequent Part A2 is not required).

 Notification to Piaggio Aero Indus tries of inspections results.
Part A2 – Restoration of FR “0” correct configuration if required:

 Radome / Nosecone removal / installation

 Lifting / removal of the Ai rplane on (from) jacks.

 Removal / installation of avionics equipm ent from nose compartment, as required.

 Removal / installation of items from (into) flight compartment.

 Installation of missing co rner reinforcements.

 Avionics / Communication / Aut opilot tests, as required.

 Pitot / Static System Le ak Test, as required. Part “B”: DELETED – A/C S/N 1002 ALREADY MODIFIED. Part C – Change introduction:

 Radome / Nosecone removal / installation.
