Supplemental Structural Inspection Document
This section and AMM 12-B-05-10-30-00A-280A-A give the additional structural and component life limits and the
supplemental inspections needed for aircraft that have 25,000 flying hours or 30,000 landings or more and forms
the Supplemental Structural Inspection Document (SSID) needed to increase the life of the airframe.
Service Bulletin 04-009 must be accomplished to allow an aircraft to be operated up to 25,000 flying hours or
30,000 landings, whichever comes first.
Note
Before starting implementation of SB 04-009 and/or the SSID, a suitability assessment performed by Pilatus is
recommended to establish any potential resulting limitations related to the aircraft condition at time of the life
extension. Contact Pilatus for the lead time of the Pilatus support activities as listed in
www.pilatus-aircraft.com -> contact.
In addition, it is recommended to have a Pilatus on-site representative when performing the first life extension.
Note
The tasks of the SSID inspections may be scheduled as per the customer’s needs provided that the thresholds and
inspection intervals are not exceeded.
5.1
Limit of Validity
The limit of validity (LOV) of the SSID is 50,000 flying hours or 60,000 landings, whichever comes first. The part
of the SSID for the wing structure (without systems and control system structure such as flaps and ailerons) has a
lower LOV of 35,000 flying hours or 43,000 landings, whichever comes first.
5.2
Authorisation
The following is required to do the SSID:
−
Latest PC-12 ALS and referenced AMM/SRM data modules and CMM
−
Adequate ground support equipment and tools
−
Licensed NDI inspectors Level II or higher
