Installation, Commissioning & Repowering
Repowering Packages
Engine, gearbox, mounts, controls, cooling and exhaust arrangement quoted and delivered as one scope, with the propeller match calculated rather than assumed.
Features
- Quoted as a scope of work rather than a parts list, so responsibility for the propeller match and the trial result sits in one place.
- Propeller re-pitch or replacement is included in the calculation, because a new engine speed with the old propeller is the commonest repower disappointment.
- Cooling, exhaust and ventilation are sized for the new engine's heat rejection rather than reused unchecked.
- The programme is built around the yard slot, with long-lead items identified at the start.
- Handover includes the trial record, the settings, the spares list and the service schedule for the new installation.
