MAINTENANCE AND INSPECTION OF AIRCRAFT
50X1
1. Source stated the following maintenance procedure: The maintenance
personnel of each individual flight inspected and maintained only
the aircraft assigned to them within the individual flights. Per-
sonnel of one flight were not permitted to inspect and or maintain
aircraft in any but their assigned flight. The maintenance and
technical personnel were paid according to the job they did.
PRE-FLIGHT INSPECTION AND MAINTENANCE:
2. This inspection and maintenance was made by two mechanics. they
inspected the engine and the aircraft, also performed engine run-up
and complete operational checks. The technicians from the same
flight would check the equipment of their own specialty. For inStance,
the radio technicians had to take care of their own detailed inspec-
tion and maintenance. The armament man took care of the guns and
loaded them only when the aircraft was going to fly a gunnery mission.
This entire pre-flight inspection generally took around two hours
although much depended on the malfunctions found by maintenance
personnel.

POST FLIGHT INSPECTION AND MAINTENANCE:
3. This inspection was made in the same manner as the pre-flight inspec-
tion. The same personnel took care of both the pre-flight and post-
flight inspection. The armament man had to remove the gun clips and
clean the guns thoroughly. Each technician and his assistant had
to visually inspect, clean, and take care of his section of the air-
craft.
ENGINE OPERATIONAL CHECKS:
4. When the aircraft was grounded or did not fly for seven days, a
complete engine and operational check had to be performed. The
mechanics had to perform run-ups and control sueface checks. Each
technician and his assistant had to perform his own inspection and
operational check.
PREPARATION FOR SUMMER OPERATION OF AIRCRAFT:
5. This preparation was scheduled to be performed yearly between 15-6:.,
March and 15 April. Maintenance and technical personnel had to per-
form their own detail job within their specialties. Mechanics
changed winter engine oil and replaced it with summer oil and replaced
the winter hydraulic fluid that operated the servo boost flap control
and landing gear system. All winter grease was cleaned and wiped
from all nuts, bolts and movable control parts throughout the entire
aircraft and replaced with summer grease or lubricant. Armament men
had to clean thoroughly all winter grease from nuts, bolts and movable
parts of the gun section, including the gun itself; and prepare it
for summer operations. Electricians prepared their septions of the
aircraft for summer operation. Each technician thoroughly cleaned and
prepared his section for summer operation.
PREPARATION FOR WINTER OPERATION OF AIRCRAFT:
6. This was done in the same manner as the summer preparation and was
accomplished yearly between 15 October and 15 November.
Source stated that the winter and summer preparations took approxi-
mately from six to eight days per aircraft for winterizing and six
to eight days for summerizing.
DAILY AIRCRAFT STATUS LOG:
7. See Source's memory sketch of the daily aircraft status log ffncl. ]1_7.
This log was filled out at the completion of each day and turned over
to the engineering officer of the regiment; from there, it was turned
over to the engineering officer of the division.
CANNIBALIZATION OF AIRCRAFT PARTS:
8. Sourcewtateethe four MIG-15's from the first flight
50:0 of the were scheduled for a training flight,
the maintenance was done as follows: if three out of the four air-
craft were in condition to fly and the other one was AOCP, this
single aircraft would be put in commission by getting parts cannibal-
ized from an aircraft in another flight but only if the aircraft from
that flight was in maintenance and inspection status. When the air-
craft with cannibalized parts came back from its training flight,
the part or parts had to be immediately removed and returned to the
original aircraft. Source stated that this was unauthorized. for
