ACCEPTANCE INSPECTION. - This inspection is performed at the time the reporting custodian accepts a newly assigned aircraft, from any source, and on return of an aircraft from SDLM or other major depot-level rework. It includes an inventory of all equipment listed in the aircraft inventory record (AIR), verification of cartridge-actuated devices (CADS) and aircrew escape propulsion systems (AEPS), a configuration verification, hydraulic fluid sampling, a daily inspection, and a complete functional check flight. For acceptance inspection purposes, verification of CADS, AEPS, and configuration is accomplished by visual external inspection and record examination only. Disassembly beyond the daily inspection requirements of applicable PMS publications is not required. Activities may elect to increase the depth of inspection if equipment condition, visual external inspection, or record examination indicates such action is warranted.

TRANSFER INSPECTION. - This inspection is performed when a reporting custodian transfers an aircraft, including transfers to SDLM. (An aircraft sent to SDLM does not constitute a transfer unless directed by an aircraft transfer order [ATO].) A transfer inspection includes an inventory of all equipment listed in the aircraft inventory record (AIR), a verification of the configuration, hydraulic fluid sampling, and a daily inspection required by the applicable PMS publication. Activities may elect to increase the depth of the inspection if the equipment condition indicates such action is warranted.

TURNAROUND INSPECTION. - This inspection is conducted between flights to ensure the integrity of the aircraft for flight, to verify proper servicing, and to detect defects that may have occurred during the previous flight. The turnaround inspection is considered valid for 24 hours, provided that no flight and no maintenance, other than servicing, occurs during this period.

PREFLIGHT/PREOPERATIONAL INSPECTION. - This inspection is conducted before each flight and/or operation to verify that the equipment has been properly serviced, and to detect defects that would have an adverse effect on the flight and/or operation. This inspection is valid for 24 hours, provided no flight and no maintenance, other than servicing, occurs during this period.

POSTFLIGHT/POSTOPERATION INSPECTION. - This inspection is conducted immediately after each flight and/or operation to determine defects that may have developed during the flight and/or operation.

DAILY INSPECTION. - This inspection is conducted to inspect for defects to a greater depth than the turnaround or preflight inspections. When all preflight requirements are contained within the daily card set, accomplishing the daily requirements before the first flight of the day satisfies the preflight inspection. A daily inspection is performed before the first flight of the day. It may be considered valid for a period of 72 hours, provided that no flight occurs during this period and that no maintenance, other than servicing, has been performed.

SERVICING. - Servicing requirements provide for replenishment of fuel, oil, and other consumables expended during a flight.

SPECIAL INSPECTION. - An inspection with a prescribed interval other than daily, calendar, or phased. The intervals are specified in the applicable PMS publication. They are based on elapsed calendar time, flight hours, operating hours, or number of cycles/events; for example, every 7 days, 28 days; 50, 100, 200 hours; 10, 100 arrestments; 5,000 rounds fired, etc.

CONDITIONAL INSPECTION. - This inspection is an unscheduled inspection that is required as a result of a specific overlimit condition, or as a result of circumstances or events that create an administrative requirement for an inspection. A logbook entry is required for conditional maintenance requirements that prescribe inspections to determine equipment condition; for example, airframe hard landing, precarrier, predeployment, aircraft ferry, acceptance, transfer, and engine overspeed and overtemp inspections. Those conditional requirements that specify servicing or fluid sampling need not be logged.

CALENDAR INSPECTION. - This inspection is a thorough examination of the aircraft. It is conducted at predetermined calendar periods of time, such as 13, 15, or 17 weeks etc., as assigned by higher authority.

If the odd/even calendar inspection concept is used, certain maintenance requirements are scheduled only every other calendar period. The
