5.13.1.2.8 Block 7, AIRFRAME TIME: Upon initiation of a new form, transcribe the total time from the TOTAL block of
the previous form to the PREVIOUS block of the new form. Ensure the airframe time is updated in the AFTO Form 781J.
At the completion of each flight, record the flight time pertaining to the date involved in the appropriate flight blocks.
Aircraft with automated flight data recording systems will utilize the data provided by the automated flight data recording
system. Add these entries for a new total entry in the block at the end of the specified flying period.
5.13.1.2.9 Block 8, LANDINGS: Use this block to record previous FULL STOP, TOTAL, and LANDING GEAR
CYCLES on aerospace vehicles for which maintenance or inspection of the landing gear system or components is based on
a specified number of landings/gear cycles. Maintain a separate record of full stop landings for aerospace vehicles under this
criteria. The aircrew will document total landings, which include full stop landings, in the TOTAL column and document
only the full stop landings in the FULL STOP column. These entries will be added for a new total entry in the TOTAL block
at the end of the specified flying period. If applicable, aircrew will also document LANDING GEAR CYCLES (gear full
up/full down). Aircraft with automated flight data recording systems, will utilize the data provided and stored by the
automated flight data recording systems in accordance with MDS specific guidance.
5.13.1.2.10 Block 9, CART/JFS STARTS: For aircraft/engines with cartridge/JFS start capability, maintain a history of
cartridge/JFS starts to determine starter time change. The aircrew will document in the CART/JFS START column by engine
number, the number of cartridge/JFS starts for each flight. Maintenance personnel will document each ground cartridge/JFS
start. These entries will be added for a new total in the TOTAL block at the end of the specified flying period. This total will
be carried forward to block 9, PREVIOUS of the new AFTO Form 781H.
5.13.1.2.11 Block 10, ENGINE CYCLE DOCUMENTATION: For selected engines listed in TO 00-25-254-1, maintain a
history of cycles for compressors, turbine disks, and other designated components to determine fatigue life. The aircrew will
document cycles which have occurred during the flight, on the FLIGHTS line. The definition of cycles for each engine is
included in the applicable aerospace vehicles MDS specific -1, -2, and -6 TOs and the appropriate engine TO and mainte-
nance manual. Aircraft with automated flight data recording systems, will utilize the data provided and stored by the
automated flight data recording systems.
NOTE
When blocks 8, 9, 10, 11 and 12 are not used line out the printed words and use the blocks for other purposes as
approved by the GP/CC.
5.13.1.2.12 Block 11, SERVICING DATA: Servicing data is grouped into four basic categories: FUEL, OIL, OXYGEN
AND NITROGEN/WATER. A dash in servicing rows will indicate that in-tank checks have not been complied with or are
not required. For example, if only fuel is checked or serviced, put a dash in the servicing rows for OIL, OXY, and
NITROGEN/WATER blocks and carry down previous in-tanks totals. Specific entries are as follows:
5.13.1.2.12.1 OCTANE or GRADE: For each servicing line, enter the fuel grade/octane with which the aerospace vehicle
was serviced. Example: JP-8.
5.13.1.2.12.2 QTY SRVCD: Enter the total quantity of fuel (Pounds, Gallons or Liters) serviced or drained at one
operation. If no service is required, enter a “0” (zero) to serve as a positive indication that the tanks have been checked. To
indicate the unit of measure being used for the QTY SRVCD and TOTAL IN TANKS entries, enter “P,” “G,” or “L,” which
will indicate pounds, gallons or liters, as a part of the serviced or in tanks entry. Example: 2,750P or 6,243G. Enter total
pounds, gallons or liters of fuel drained in red and carry a minus sign prefix. Example: -250G. Record fuel taken onboard,
fuel dumped overboard, fuel off loaded or oil transferred from an auxiliary tank to an engine or engines during flight, as a
separate service in the next open row. Enter the quantity of fuel dumped or off loaded in red and carry a minus sign prefix.
The aircrew or other aircrew member will make these entries for in-flight operations.
5.13.1.2.12.3 TOTAL IN TANKS: Upon completion of servicing, draining or completion of an in-tank check, enter the
total number of pounds (P), gallons (G) or liters (L), of fuel onboard in all tanks (excluding in-flight refueling tanks of tanker
aerospace vehicles). Enter a separate line entry when a different grade of fuel is onboard other than that of the aerospace
vehicles.
5.13.1.2.12.4 OIL (Half pints, pints, quarts, gallons or liters): Line out the non-applicable words from the title of this
column to indicate what units of measure are being used and list the type and/or specification of the oil serviced to the right
of the title, if different than what the TO calls for. In the SER column of the applicable servicing number row, enter the
number of half-pints, pints, quarts, gallons or liters of oil serviced or drained from each oil tank. Record the total number of
half-pints, pints, quarts, gallons or liters of oil in each engine tank after servicing or draining in the IN column. If no in-tanks
