1 Rescue hoist lift definition. A lift is defined as an unreeling and recovery of the cable with a loadattached to the hook, independently of the length of the cable that is deployed / recovered. Anunreeling / recovery of the cable with no load on the hook is not considered to be a lift. Any operationwhere a load is attached for half the operation (i.e. unreeling or recovery) must be considered as alift.
2 When the helicopter operates in a sandy or dusty environment, multiply by two the hours ofoperation with a load attached to the cargo hook. This applies also when the helicopter is used forlogging works.

Description
1 Discard time scheduleThis section gives you the recommended replacement schedule for the non-critical part of thehelicopter. This schedule is not an airworthiness limitation.
Some parts presented in this section, with the same part number, are interchangeable among thevarious A109/A119 models. The replacement schedule for a particular part, even with the samepart number, may be different depending upon which A109/A119 model the part is installed on.The replacement schedule of parts that have been interchanged among models must use thelowest replacement time listed for any model on which that part has been installed.
The discard time specified for any given part number contained in this section applies to indicatedand all successive dash numbers for that item, if not differently specified.
When retiring from service the parts contained in this section, the relative standard parts have alsoto be retired from service.

For the scheduled maintenance inspections applicable to the optional equipment refer to 0B-A-05-70-00-00A-000A-A.
2 Scheduled inspection programsThe three inspection programs shown in Fig 1 are available. You can do the selection of theprogram you think the best one in relation to the type of your usual operations. These threeprograms give you maximum flexibility and maximum readiness of the helicopter.
3 Change of inspection programYou can change the inspection program from the one in use to another, but you must obey theinstructions that follow:
3.1 Change from standard to extended inspection programYou must:
– Do the basic 50-hour / 30 day inspections included in the extended program.– Do the 200-hour inspections included in the extended program.– Continue with the new (extended) program.
3.2 Change from standard to progressive inspection programYou must:
– Do the basic 50-hour / 30-day inspections of the progressive program.– Do the preceding phases of the 200-hour inspections of the progressive program.– If applicable, do the preceding phases of the 400-hour inspections of the progressive
program.– Do the preceding phases of the 12-month inspections of the progressive program.– Continue with the new (progressive) program.
3.3 Change from extended to standard inspection programYou must:
– Do the 100-hour inspection of the standard program.– Continue with the new (standard) program.
3.4 Change from extended to progressive inspection programYou must:
– Do the basic 50-hour / 30-day inspections of the progressive program.– Do the proceding phases of the 200-hour inspections of the progressive program.– If applicable, do the proceding phases of the 400-hour inspections of the progressive
program.– Do the proceding phases of the 12-month inspections of the progressive program.– Continue with the new (progressive) program.
3.5 Change from progressive to standard inspection program(Helicopters that have less than 400 flight hours) Obey the instructions that follow:
– Do the 100-hour inspections of the standard program.– Do the 12-month inspections of the standard program.– Continue with the new (standard) program.
(Helicopters that have more than 400 flight hours) Obey the instructions that follow:

– Do the 100-hour inspections of the standard program.– Do the 400-hour inspections of the standard program.– Do the 12-month inspections of the standard program.– Continue with the new (standard) program.
3.6 Change from progressive to extended inspection program(Helicopters that have less than 400 flight hours) Obey the instructions that follow:
– Do the 200-hour inspections of the extended program.– Do the 12-month inspections of the extended program.– Continue with the new (extended) program.
(Helicopters that have more than 400 flight hours) Obey the instructions that follow:
– Do the 200-hour inspections of the extended program.– Do the 400-hour inspections of the extended program.– Do the 12-month inspections of the extended program.– Continue with the new (extended) program.
3.7 Change of inspection program - ExampleThe procedure that follows is an example of the change from the extended inspection program tothe progressive inspection program.
The inspection program is changed 580 flight hours and 9 months after the last 12-monthinspections of the extended inspection program. To change the inspection program, you must:
– Do the basic 50-hour / 30-day inspections of the progressive program.– Do phases A, B and C of the 200-hour inspections of the progressive program.– Do phase 1 of the 400-hour inspections of the progressive program.– Do phases I and II of the 12-month inspections of the progressive program.

1 Rescue hoist lift definition. A lift is defined as an unreeling and recovery of the cable with a loadattached to the hook, independently of the length of the cable that is deployed / recovered. Anunreeling / recovery of the cable with no load on the hook is not considered to be a lift. Any operationwhere a load is attached for half the operation (i.e. unreeling or recovery) must be considered as alift.
