copy shall be kept along with Journey Log Book.
d. The CAM shall be responsible for the proper maintenance of logbook. Omission to
make Log Book entries shall render the aircraft, engine, propeller, radio apparatus
as un-airworthy and the authorized officer of the Regional Airworthiness Office may

3CIVIL AVIATION REQUIREMENTS SECTION 2
SERIES X PART VI ___ AUGUST 2023
e. Entries in the Log Book shall be made in ink or indelible pencil and signed and dated
by appropriately licensed AME/Approved individual carrying out the work or by a
person, specially authorized by DGCA for the same, quoting, beneath the
signature, the Licence/Approval/ Authorization number.

records are computerized, hard copies may not be required. The operator should
satisfy and demonstrate the accuracy of the system and procedure for creating
backups to the Regional airworthiness office. The procedure of using computerized
records shall be documented in the CAME or equivalent document.
9. RECORDING OF FLIGHT TIME FOR THE PURPOSE OF MAINTENANCE PLANNING: -
a. Flight Time:
(i) In respect of an aeroplane, means the total time from the moment the aeroplane
first moves for the purpose of taking off until the moment it finally comes to rest at
the end of the flight
(ii) In respect of a helicopter, means the total time from the moment the helicopter’s
rotor blade start turning until the moment it finally comes to rest at the end of the
flight, and the rotor blades are stopped
Note: Flight time as herein defined is synonymous with the term “block to block” time,
or “chock to chock” time in general usage which is calculated from the time an
aeroplane first moves for the purpose of taking off until it finally stops at the end of
the flight.
b. Flight time for the aircraft, engine, VP propellers and radio apparatus shall be
recorded in the appropriate Log Books.
Note: Where the manufacturer has defined maintenance periodicity on the basis of
actual Flight Time i.e Chocks OFF to Chocks ON or any other consideration like
power etc., operator may follow the same with approval of Regional Airworthiness
Office. The approved CAME should detail the procedure followed for calculating the
flight time for the purpose of maintenance of aircraft and components.
10. CERTIFICATE OF RELEASE TO SERVICE:
a. All work involving repair, overhaul, replacement, modification, special
inspection performed on the aircraft, is required to be covered with the issuance of
"Certificate of Release to Service" signed by an appropriately licensed
AME/Approved or authorised individuals.
b. Significance of signatures in the Log Book :
Signatures appearing in the appropriate column of Log Book against the relevant
entry shall be taken as issuance of certificate, signifying that the work has been

performed in accordance with approved procedures, using approved equipment
and material and in accordance with the directives issued by DGCA.
Note: Guidance for electronic logbook, electronic signature, records and documents is
given in AAC 4 of 2023.
c. Overhauls:
Details of overhaul work, including any test data, should be entered in the
appropriate Log Book. A Certificate of Release to Service must be appended to the
entry for all overhaul work recorded in log books. Test data should be preserved
with cross-reference in the logbooks for traceability.
d. Repairs:
A summary of the repair should be entered in the appropriate log book, together
with an indication of the reason for the repair. Details of repair work should be
preserved with cross-reference in the logbooks for traceability.
e. Replacements:
When a component having its own log book (i.e. an engine or a variable-pitch
propeller) is removed from an aircraft, the reason for removal should be entered in
that log book, e.g. 'metal in oil filter', 'time expired'. In addition, an entry should
be made in the aircraft log book stating the serial number of the component
removed, the serial number of the replacement component and the position the
component occupies on the aircraft.
When an engine is changed, the hours flown and the serial numbers and part
numbers, as appropriate, of lifed parts, which are not changed with the engine,
should be entered in the log book of the replacement engine and in the aircraft
log book.
When a component, not having an individual log book, is removed, the reason
for removal and its serial number, and in some cases the part number, of the item
should be entered in Aircraft Log Book and also, with the exception of standard
parts such as split pins, nuts and washers, the origin and numbers of release
note.
When a serviceable part is removed from one aircraft and fitted on to another, the
number of flying hours logged for the part should be entered in the appropriate log
book together with an identification (i.e. registration letters) of the aircraft/ engine
from which it was removed.
Where a replacement involves disturbing a flying or engine control system, or
any system associated therewith, an independent inspection as covered in CAR M
must be carried out and a certified entry to that effect included in the log book.
11. MODIFICATIONS:
5CIVIL AVIATION REQUIREMENTS SECTION 2
SERIES X PART VI ___ AUGUST 2023
After embodiment of a modification, an entry must be made in the appropriate
Log Book quoting the number and title of the modification, as applicable.
Whenever a major component is changed, the modification standard, particularly
in regard to mandatory modification of the replacement component should be
entered in the appropriate log book.
12. CARRIAGE OF LOG BOOKS ON BOARD:
Journey log book and technical log/ flight log or ‘Flight Report Book (FRB), as the
case may be, shall be carried on board during flight unless the aircraft is engaged
in local flights i.e. making a series of flights over the same airport, on any day. Other
log books shall not be carried during flight and shall be maintained at the main
base. However, if an aircraft is likely to remain away from its main base, where Log
Books are maintained, "working copies” of Log Books giving necessary information
as required for effecting due maintenance shall be carried on board. On return
to main base, entries shall be transferred from the "working copies" to the regular
Log Book, within 48 hours of the return to main base.
13. PRESERVATION:
Log Books shall be preserved for the periods shown as under:
a) Aircraft Log book
i. The aircraft log books shall be preserved until such time as the aircraft is
permanently withdrawn from use and its Certificate of Registration is cancelled by
the Director General.
ii. In case of an aircraft meeting with an accident resulting in damage beyond
economical repairs to the aircraft, engine, propeller, the aircraft log book, engine log
book and propeller log book shall be preserved for a period of two years after the
date of the accident.
b) The engine and propeller log books shall be preserved until such time as the engine/
propeller is permanently withdrawn from use.
c) Journey log book and technical log/ flight log or ‘Flight Report Book (FRB)’, as the
case may be, shall be retained for 36 months after the date of the last entry.
d) Other log books shall be preserved for two years from the date of the last entry
therein.
e) Where log books in respect of aircraft, engines or variable pitch propellers or
radio apparatus are not kept in the manner and form prescribed in this CAR, the
aircraft shall be deemed as not being maintained in an airworthy condition.
