requiring the monthly compilation of significant operating data. Reporting custodians ensure that operating or monitoring system data is entered on this form at a monthly interval and upon transfer of the equipment.

The Equipment Operating Record provides columns for logging operating hours or monitoring system data, as applicable. Uncaptioned columns are provided for monitoring system data and are labeled as required; for example, starts, rounds fired, low cycle fatigue (LCF), and meter reading. If equipment is monitored by time since new (TSN) and time since rework (TSR), the first column under monitoring system data is labeled TSR. The accumulative column under operating hours shows the TSN hours. A remarks column has been provided for logging special information, as appropriate. Operating hours are obtained from record type (RECTYP) 7B of the naval aircraft flight record.

Inspection Record (OPNAV 4790/22A)

The Inspection Record shown in figure 6-4 of chapter 6 is one of the forms that is common to both the aircraft logbook and the AESR. (NOTE: As you read portions of this chapter, you will be referred to some of the figures shown in chapter 6 because they are used in both the aircraft logbook and the AESR.) The maintenance of the form is essentially the same for both records. The heading blocks on each form should be filled in to identify the type of inspection (periodic or conditional), and the equipment name, model, and serial number should be entered on each form. Types of actions that require an Inspection Record entry are described below.

This form reflects all inspections on equipment, including those in aircraft phased maintenance requirements cards, with the following exceptions-preflight, postflight, turnaround, daily, preoperational, and oil sampling.

All major engine inspections, calendar, phase, special, and conditional inspections (except fluid sampling, engine wash, or servicing) require AESR entries by the activity performing the inspection. Phase, calendar, and major engine inspections are maintained on one page. Special and conditional inspections are maintained as separate pages within this section of the AESR.

If an inspection requires nondestructive inspection (NDI) or disassembly and reassembly, the inspection is logged on an inspection record form titled "SPECIAL" on other equipment having an AESR.

A entry is made in the reference column for each inspection that indicates the NAVAIR or major command directive that requires the applicable inspection.

Conditional inspections are unscheduled events required as a result of an overlimit condition, or as a result of circumstances or events which create an administrative requirement for an inspection, such as a hot start, overtemp, and acceptance or transfer of an aircraft. They require an Inspection Record entry.

Acceptance and transfer inspections on uninstalled equipment are not required.

During repair or rework, the intermediate maintenance activity (IMA) or the depot (D)-level maintenance activity screens this section of the AESR. The old inspection record pages for scheduled maintenance will be removed and a new record containing the data necessary for determining when the next inspection is due will be initiated. The Conditional Inspection pages are screened for items of historical or maintenance value and transcribed to a new page. A minimum of 2 years data will be maintained at all times on the Conditional Inspection page.

Repair/Rework Record (OPNAV 4790/23A)

The Repair/Rework Record is a permanent part of the AESR. It contains a complete record of all repair, reconditioning, SDLM, conversion, modification, and modernization performed on the equipment by any IMA or D-level maintenance activity. In all cases where an item requires an AESR, the AESR will accompany the equipment through the maintenance action required and will be updated by the activity accomplishing that action. This form is the same one that is shown in figure 6-5 of chapter 6.

Technical Directives Form (OPNAV 4790/24A)

The Technical Directives Form is used for the recording of technical directives in the AESR. This
