Firefighting aircraft are regularly overhauled by the Aeronautical Technical Center at the end of each firefighting season. The overhaul works include:
a) Scheduled maintenance up to and including 72 months inspection NDT inspections (i.a.w. A/C manual),
b) Unscheduled maintenance (AD, SB, SL, AOM, RO, Alert),
c) Engine hot section inspection (HSI).
d) Ramp tests and inspections,
e) Line maintenance interventions and assistance.
During the firefighting season, rapid intervention units stand by and are dispatched to air bases when needed. Mobile workshops have been organized in order to provide on-site repair sevices and technical assistance.
