systems equipment, rockets and electronic systems\). Some systems may require an inspection requirements manual only, or work cards only. For other systems a combination of both inspection manual and work cards may be more suitable.

MIL-DTL-5096G

Inspection, Minor Inspection and Major Inspection. This section shall primarily include requirements

that fall in the following categories:

a. Items that are subject to developing defects after periods of operation in excess of the hourly

postlight/postoperation inspection interval and may require disassembly to ascertain wear or

deterioration that may cause failure of the unit.

b. Items that due to their function within a system require a periodic examination or servicing less

frequent than the hourly postlight/postoperation interval or in some instances, less frequent

than the basic periodic/phased/isochronal inspection interval to detect impending failure or a

servicing requirement.

c. Items that require periodic removal for bench check to determine functional reliability, extent of

physical wear, and evidence of incipient failure.

d. Items that require less frequent veriication of service than the hourly postlight/postoperation

interval.

3.2.2.3 Chapter 2, Special Inspection and Maintenance Requirements. Special inspections shall include those

functions to be accomplished at the expiration of a speciied number of lying hours, equipment hours of

operation, and lapse of calendar time. The special inspections shall also include those functions to be

accomplished after the occurrence of a speciic or unusual condition or incident, and when accepting an

aircraft after extensive modiications. Unless otherwise speciied by the acquiring activity (see 6.2k.), all

sections listed in paragraphs 3.2.2.3.1 thru 3.2.2.3.4 shall be used. When not required, they shall be included

and marked "Not Applicable." When speciied by the acquiring activity (see 6.2l.), additional sections

shall be included and shall begin after the last required section. They shall be of the type speciied

by the acquiring activity. Data shall be formatted in accordance with Figures 3 thru 6 with appropriate

wording for the type of inspection and equipment.

3.2.2.3.1 Chapter 2, Section I - Special Inspections after a speciic occurrence (see Figure 3). These

inspections shall be designed to meet the following criteria:

a. Items that due to their physical characteristics are subject to deterioration after long periods

of service.

b. Items that due to their structural characteristics are subject to fatigue after long periods of service.

c. Items that due to their function within a system are subject to damage from speciic events, such

as hard landings, violent maneuvers, hot starts, false starts, etc.

3.2.2.3.2 Chapter 2, Section II - Depot (see Figure 4). The depot section shall include inspections and

maintenance to be accomplished on a scheduled calendar time cycle basis. Inspection requirements shall

insure that all accessible areas and components not afforded coverage at other inspection intervals are given

thorough and adequate attention. Work cards to detail these requirements shall be prepared. This chapter

and section also includes Programmed Depot Maintenance (PDM).

3.2.2.3.3 Chapter 2, Section III - Acceptance and Functional Check Flight (FCF) inspection requirements

(see Figure 5). This section shall list those conditions which require a functional check light to verify

maintenance performed on the aircraft or its airworthy condition. Speciic conditions for FCFs shall be

determined for each aircraft, based upon technical conditions and operational experience. It may also

be necessary to prescribe FCFs for component changes such as engines or major light control surfaces

when the possibility of failure or a malfunction of the component is greater during its initial period of

operation. These types of requirements shall be related to experience factors on component failures or

malfunction rates, the number of like components installed in the aircraft, the number of these items that

could be changed simultaneously without creating an unacceptable safety of light risk, and whether or not

an emergency backup system is provided for use in the event of a failure of the main system. This section

shall include requirements that fall in the following typical conditions:

a. After a periodic or speciic numbered phase, i.e., sixth and twelfth inspection has been completed.

If a complete functional check light inspection has been accomplished within 150 hours of a

sixth or twelfth phased inspection, no functional check light inspection will be required.
