Completion of compass calibration. One of two entries is required. The correct entry depends on whether the compass is in or out of limits (see OPNAVINST 4790.2 for specific statement). As a minimum, record the type of compass calibrated, method of calibration, date compass was calibrated, and location where calibrated. Acceptance or transfer. An entry should be made that states that flight hours on the Monthly Flight Summary page and operating hours on the Equipment Operating Record have been verified to be correct. A minimum of 2 years of data should be maintained in the Miscellaneous/History record. OPNAVINST 4790.2 contains a complete listing of situations that require a Miscellaneous/History page entry. OPNAVINST 4790.2 also includes the specific wording to be used for each situation. Q20. An entry on the Miscellaneous/History record of the aircraft logbook should be made upon receipt and transfer of an aircraft that states that what two records have been verified to be correct? PRESERVATION/DEPRESERVATION RECORD (OPNAV 4790/136A) This form is used in three records—the aircraft logbook, AESR, and MSR. The form is used to document preservation, represervation, and depreservation on aircraft or equipment. Entries are also required on uninstalled equipment if preservation MRCs or Preservation of Naval Aircraft, NAVAIR 15-01-500, specifies a preservation requirement. Aircraft preservation requirements, including type and length, can be found in applicable MRCs. Figure 6-10 shows a Preservation/Depreservation Record. The Preservation/Depreservation Record is self-explanatory. Information required to make entries on this record is obtained from the MAF. INSTALLED EXPLOSIVE DEVICE RECORD (OPNAV 4790/26A) The Installed Explosive Device Record form contains a record of all explosive devices currently installed in the aircraft. These include, but are not limited to, lap belt cartridges, initiators, canopy release, and seat ejection cartridges or devices. This form is shown in figure 6-11. Figure 6-11 shows an Installed Explosive Device Record for an activity that uses the Survival Equipment Asset Tracking System/Increased Capabilities System (SEATS/ICAPS). SEATS/ICAPS is an automated system designed to standardize the management and reporting of Survival Equipment and Cartridge-Actuated Devices (CADS). SEATS is a database management system that provides users with an accurate means to process, store, and retrieve information on Aviation Life Support System (ALSS) items, such as parachutes. The SEATS program will be discussed later in this chapter. ICAPS is an database management system that provides users with a quick and accurate means to process, store, and retrieve information on cartridges, CADS, and aircrew escape propulsion systems (AEPS). The ICAPS subsystem give users an automated method to perform the followings: Manage CADs and AEPS assets Generate reports and schedule workloads Maintain CADs and AEPS maintenance histories Print computer-generated Installed Ex- plosive Device Record (OPNAV Form 4790/26A) forms The program also lists all CADS used Navy-wide, and includes a part number and Department of Defense Identification Code (DODIC) index for each. In addition, the system automatically computes CAD service life expiration dates when the lot number and container open date data blocks have been completed. All entries on the Installed Explosive Device Record are self-explanatory except the expiration date. The procedures used to compute expiration dates are outlined in General Use Cartridges and Cartridges Actuated Devices (CADS) For Aircraft and Unique Aircraft Systems, NAVAIR 11-100.1.1, Aircrew Escape Propulsion System (AEPs) Device, NAVAIR 11-85-1, and Cartridges and Cartridge Actuated Devices for Bomb/Racks/Launchers, Bomb Dummy Units and Airborne Missile Systems (CADs), NAVAIR 11-100.1.3. When installed explosive devices have extensions granted, you should update the ICAPS module database and print a new Installed Explosive Device Record. The authority that granted the extension (such as the message date-time group [DTG] and originator and/or 6-17
