A double asterisk (**) indicates "Inspections, hydrostatic test, and life limits will be accomplished as set forth in Part 173,
Chapter 1, Subtitle B of CFR 49 currently in effect. For foreign manufactured containers identify, retire and test per manufacturer's technical data currently in effect.
Abbreviations used in the Nord 262A Operations Specification Aircraft Maintenance are defined as follows:
OC = On Condition. [For the definition of On Condition, refer to Advisory Circular AC121-1A.] CALIB = Calibration check. Testing for compliance with established standards and readjustment for tolerances as necessary. May be performed with unit installed or removed with proper test equipment.
FC = Functional Check. A qualitative check of a component, assembly or system to determine that it is operating in a normal and intended manner.
Does not require quantitative values and is usually accomplished without removal from aircraft.
Annual Functional Checks shall be performed during the 90-day period preceding the season of maximum system usage.
BC = Bench Check. The removal of a unit from its position on the aircraft, engine or assembly and its routing to a shop for a thorough inspection, check of its performance and compliance with tolerances as prescribed for any and all of its functions. This check shall include minor adjustments, markings and lubrication.
E.O. = Engine Overhaul.
E.O. = Engine Change.
