lo A repair shop for conventional piston and jet engines was located in the forenr
German Air Force technical school in the northern portion of the Jueterbog-SI-tes
lager airfield, 13nilding No 7 housed a repair hangar, the. chief of which was a
colonel. Cl) From 4 to 7 Soviet workers in addition to 20 military technical
personnel coananded by a major were assigned to this repair hangar, The military
personnel were billeted in the former air force technical school. Usually 11,10
aircraft and occasionally MiG-1,5s were seen in the repair hangars, in late jUnes
source observed four Na-108; the engine of one was being replaced,
2, The test stand for jet engines was put in operation in June. Source observed the
engine of a tyse-27 plane being tested there,, The .former disassembly shop o:?2 the
German air Fsrcei, which was used as a material depot, was occupied by Unit
Tashov.: Source saw aluminum sheets, iron rads, electric cables, aircraft radio sets
and parachutes stored in this shop, apparently a technical installationi,r. as was
inferred fror the first word of an inscription on the wall of the shop. Ihe
parachutes of the flying personnel were hauled from this shop to the aircraft at
the field. (2)

In June, eoures oats many officers including three generals atand ing around this
plane. In the ool:::ese of their conversation, source overheard the word "neft",.,
;Ihen the ITiG-15 .v:as started, source observed that a light white rio1a instead of
the usual hot air ecanated from its jet.. The light smoke continued to be bleam out
while the plaile was in the air. IliGe15 was joined in the air by three other

4. Then 1.1iG-15S 'sore disasserbled in workshop No 79 source observed that. the rear
section of the fuselage was disengaged near the trailing edge of the wings, The
engine seen was similar to the Nene engine. The long jet tube was, trucked to the
aircraft engiee repair shop. Tie jet engine itself was not removed from the plane,,
and source clearly observed the turbine wheel.

?shape of a large oil pan extending from the air exhaust es far as the landing
gear door was removed. Thereupon a supporting trestle, the upper sections of
which Were provided with leather upholstery was pushed below the jet engine.
The trestle had recesses corresponding to the largest cross section of the jet
engine and the cross section of the jet tube. After the fastening screws of the
engine were loosened, the engine fixed on the trestle was removed to the rear.
The front section of the jet engine Observed had a much larger cross section than
its rear section. The engine was taken to the test stand and remounted in the plane
on the same day. Three hours were required for both the remova),. and remounting of
the engine. (4)
NiG-15 and type-27 aircraft are started electrically by means of a generator about
100x120x7C centimeters in size which is mounted on a threeeWheeled carriage towed
by a truck. A hand wheel with an indicator and a scale exactly of the same type as
the hand wheel on resistors of electric motors was fitted on top of the box housing
the generator, epparentlyfrom a fiveepole plug, a rubber coversd cable extended to
a socket located under the right wing about in line with the lending flap of
7!iO-15s. In most cases, type-27 planes had only their starboard engine connected to
the generetor. The socket was located slightly forward of the landing gear door.
After the plug was inserted, a singing tope with a gradually rising pitch VAS
heard for a period of about two minutes. This was followed by E light blubbering
which rapidly changed into the normal sound produced by running 'jet engines. The
pilot thereupon throttled the gas, the plug was removed, the pilot again opened
the throttle, accelerated the engine fur A short time and then taxied away. This
procedure lasted for three or four minutes. After the starboard engine of type-27
planes was started the port engine was started without the help of the starter
carriage. )Tter being started, the 7i0-15 taxied to the take-off point, while the
type-27 planes were towed there and started only at the ? take-off point. The starter
set has no motor. The IL-108 were started by means of compresaed air. The starting
device consists of two compressed air bottles mounted on a carriage-(5)

7. The crew of type-27 planes consists of four afficers. Three men board the plane
through the entrance hatch over the pilctos seat, while the rear gunner enters his
station through a hatch in the under side of the fuselage. The rear gunner is seated.
The rear guns are separated by a metal cowling which can be lowered. Sometimes two
nen were Observed in the rear gunnerts station. When the plane took af, the
bombardier was seated, However, it appeared that he took a prone position after the
plane had become airborne. (6)
.8, On type-27 aircraft and an one type-30 plane source observed different types of
antennas and rods on the under side of the rear fuselage. Source believed that one
of these rods actually was the barrel of a weapon because it was seen in different
positions. The aircraft seen were fitted with a blue blister on the under side of
their fuselages. The purpose of the blister was not determined. (7)
9,, Source once Observed that the rear section of a type-27 plane had a joint slightly
aft of the trailing edge of the wine. The rear section of the fuselage was pulled
back by about 10 centimeters, and SOMP work was then performed within the recess.
However, the rear section was not removed in the same manner as observed with
ri0-15s. (8)
10, 17esides the usual position lamps the planes carried position lamps fitted on both
sides of the engines. Type-27 planes were always refuelled through the filling
hole fitted on the upper side of the fuselage slightly aft of the cabin0 source
once Observed that a plane which had made a 45?minute flight took 45 minutes for
refuelling. (9)

11, Type-27 planes were fitted with auxiliary wine tip tanks havin a ?
maximum diameter of 60 centimeters and projectine beyond b'oth the leading
and trailine edees, The technical personnel assiened te one type-27 plane
consists of one officer and two or three men. Source 6cserred that the
crews and technical personnel of tap planes were loaded on one truc:e. The
truck was occupied by eight flying personnel, two officers wearing black.
overalls and four to six technical personnel. (10)
12c On occasion of maintenance work performed on or -Wo27 aircraft,
source observed a field grade officer who was carrying a thick book which
he never gave to anYbody?else. Source believes that, it was a technical
manual containine secret data on the maintenance of?aircreft engines. Source ,
stated that the planes were fitted with one cannon or nechine Fun each
between the fuselaee and the engine. Source once saw a man opening a lid
and pnllinn not a tube Which looked like the barrel of a Tiachine gun. (11)
