5. REPAIRS
The P&M GT450 airframe is deceptively simple, but like all aircraft requires skilled and qualified
attention. We do not recommend self repair or re-assembly by other than Factory approved repair
agents. No replacement parts should be fitted unless they are factory supplied and identified. All
replacements & servicing should be entered into the aircraft technical log book supplied and signed
off by a qualified inspector.
Incorrect servicing, maintenance or fitting of parts could result in injury or death.
5.1. WING
• Repairs must be inspected by a BMAA or P&M Aviation Ltd approved inspector and signed off in the

• Sail repairs are only to be undertaken by a P&M Aviation Ltd approved sail loft.
• Airframe repairs are to be by replacement only.
• Replacement parts must be obtained from P&M Aviation Ltd or their appointed agency.
• Bent aluminium tubes must never be straightened, always replaced.
• Frayed cables and cables with damaged or twisted thimbles must be replaced.
5.2. TRIKE

5.3. ENGINE REPAIR AND OVERHAUL
Repairs must be carried out using the appropriate Rotax repair manuals, parts list, tools and up to date
•
service information. Documentation may be obtained from an authorised Rotax distributor and also on the
Web:

• Repairs must be by replacement using genuine Rotax parts or by Rotax approved repair scheme only.
• Replacement parts must be obtained from P&M Aviation Ltd or Authorised Rotax aero engine distributor.
• The repaired powerplant installation must be inspected by a BMAA or P&M Aviation Ltd approved
inspector. It should be ground run to check all systems function correctly and to check for loose components
or leaks. The work carried out must be signed off in the technical log.
• Engine malfunction is more likely in the first few hours after repair and the aircraft must be operated
accordingly. Operating temperature and pressure limits must be closely monitored.
• The engine should be treated as if it were newly installed and the initial 10 hour checks should be carried
out on any assembly which has been disturbed (e.g. propeller bolt torque). Any initial checks required by the
Rotax engine service schedule should also be carried out, e.g. the initial oil and filter change.
