Part I of this form is used to record information that is established for each type/model/series (T/M/S) aircraft. Such information includes references used as well as basic life limitations, such as catapult cycles, arrestment cycles, and flight hours. Part II lists all components with life limits tracked in flight hours or calendar time, and components measured in number of catapult and arrestment/landing cycles. MONTHLY FLIGHT SUMMARY (OPNAV 4790/21A) The reporting custodian maintains the Monthly Flight Summary form. This form is designed to permit the monthly compilation of significant flight operational data throughout the service life of the aircraft. Reporting custodians must ensure that all monthly totals have been entered on this form before the aircraft is inducted into rework. This form, shown in figure 6-2, is a permanent part of the aircraft logbook. The Monthly Flight Summary form is divided into four parts. Part I contains information about an aircraft’s service period and accumulated operating service months (OPSERMOS). Only fleet support (FS) activities make entries in Part I. Reporting custodians (squadrons) use part II to record the receipt, revision, or adjustment of a service period. Period end dates (PEDs) may be adjusted when aircraft complete special rework that requires 30 days or more at a naval aviation depot (NADEP) facility or as a result of an Aircraft Service Period Adjustment (ASPA) inspection. Entries in this section reflect the ending date of the current operating service period (month and year) and the total number of OPSERMOS the aircraft has accumulated as of the ending date. Part III is self-explanatory and reflects an extension of an operational service period beyond the period end date. Extensions, when authorized, are granted in increments of 3 months. Part IV of the Monthly Flight Summary record is used to record monthly flight and landing data. All months are accounted for in chronological order. The Monthly Aircraft Utilization Report, NAVFLIRS-1, is the source of information for entries in this section of the form. Entries must be typewritten or printed in black ink. The exception to this procedure is when aircraft and logbooks are closed out and transferred. In this case, the close-out entry should be made in pencil. INSPECTION RECORD (OPNAV 4790/22A) The purpose of the Inspection Record form is-to record periodic and conditional inspections performed on the aircraft. Routine turnaround, daily, servicing, engine wash, and oil sampling are not logged in any logbook. Phase and conditional inspections are maintained on separate pages. The form, illustrated in figures 6-3 and 6-4, provides space for identification as to whether the listed inspections are periodic or conditional. The left column on the form is titled TYPE OR DESCRIPTION OF INSPECTION to facilitate proper descriptive entries for individual inspections. Phase inspections are conducted at a stipulated number of flight hours. Such inspections are entered sequentially, and should reflect the type phase and flight hours at time of inspection; for example, Phase A/4105.5. Records of this inspection are removed from the aircraft logbook at the time of standard depot-level maintenance (SDLM), and a new record is initiated. Conditional inspections are unscheduled events required as a result of a specific overlimit condition (hot start, overtemp, hard landing, etc.) or as a result of circumstances or events that create an administrative requirement for an inspection. Precarrier, predeployment, acceptance, transfer, and aircraft service period adjustment (ASPA) inspections are logged as conditional inspections. A rework activity will remove this page from the aircraft logbook upon completion of SDLM and insert a new record containing data necessary for determining when the next inspection due will be initiated. A minimum of 2 years of data should be maintained at all times on the conditional inspection page. The following inspections, performed on aircraft, are NOT logged in the inspection pages in the aircraft logbook. Inspections performed on equipment for which an AESR is required are logged in the AESR. This procedure provides one correct place in the logbook for recording any particular inspection. The procedure also ensures that inspection records for major aeronautical equipment are current and available with such equipment after the equipment has been removed from an aircraft. Bulletins that specify conditional inspec- tions are logged in the TD section of the 6-6
