(21) Preserve the engine spares (except for gaskets and rubber parts) and airborne tools with oil K-17 at
a room temperature. Wrap the preserved spares in paraffined paper, prepare the box for packaging, insert
spares into it and secure the box cover.
(22) Package the airborne tools into the case using the following procedure:
(a) Carefully inspect the case, clean it of soil by blowing with dry clean compressed air or wipe with clean
dry cloths.
(b) Place the airborne tools into the case. The tools should be securely fixed in the clamps.
NOTE: Never touch the tools with ungloved hands.
(c) Dry the case with airborne tools with dry compressed air passed through the oil/moisture separator
heated to a temperature of 60 °G and dried to a dew point of not above minus 20 °C.
(d) Insert the first bag with silica-gel dehydrator, grade KSMG and ShSMG (500 g) with up to 2 %
moisture in the case.
(e) Place the airborne tool list in the case, close and seal the latter. The locks should be positively fixed.
(f) Wrap the case with two layers of paraffined paper and fix with twine. Wrap the handles with paper
and tie with twine additionally.
(g) Secure the second bag with ailica-gel dehydrator (500 g) and the silica-gel indicator cartridge to the
case by Mac-Key threads folded six or with twine,
(h) Make a cover of polyethylene film.
(i) Place the case in the cover and fuse its edges. Evacuate air from the cover through the valve so that
the cover presses to the case and ensure tightness of the valve.
Accurately position the case in the packaging box and close the box cover,
(j) Store and check condition of the silica-gel indicator as instructed in Section 8.
(23) Enter the preservation date, operation description, preservation term, name of person in charge of

4. REMOVAL OF CORROSION FROM ENGINE PARTS
Preserve the engine for prolonged storage only after removing corrosion from parts.
(1) Remove corrosion from steel parts with sandpaper No. 170 or 230 moistened in oil MS-20 and polish
with paste GOI.
After polishing the surface, wipe it with a clean cloth moistened in gasoline, then with dry cloth and coat
with preservation grease, selected depending on the preservation term (Ref. Table 901).
(2) Remove corrosion from aluminium parts by a scraper, then dress the area with
powdered pumice or sandpaper not coarser than No. 230; wipe the parts with a cloth moistened in
gasoline, then with a dry cloth and paint the matching color or coat with preservation grease.
(3) Corrosion spreads quickly on magnesium alloy parts; therefore, immediately dress the affected areas
with a scraper, then with sandpaper not coarser than No. 230, wash with gasoline and wipe dry.
Oxidize the dressed magnesium alloy parts.
It is recommended to oxidize the parts at a room temperature in the solution of the -following formula:
Selenic acid ...................................... 20 g
Sodium bichromate ................................. 10 g
Water ............................................. 1000 ml
Exposure - 1 to 2 min.
If the parts cannot be removed from the engine, they may be oxidized by lightly rubbing with cotton wool
moistened in the solution. After oxidizing the magnesium alloy parts, dry them blowing with clean dry air and
paint the matching color or coat with preservation grease.
