The storeroom for the engine, accessories and spares should be absolutely isolated against various

8. STORAGE OF ENGINE AND SPARES AT DEPOTS
Mark the time of arrival of the engine, the date and term of original preservation (to be taken from the
engine Log Book) in the Register.
Keep boxes with spares in a separate pile (in set with engines); indicate the time of arrival, date and
term of original preservation on the pile.
Spares delivered by the Supplier are preserved for a term indicated in the accompanying documents.
This term is effective provided the Supplier's preservation is completely intact, therefore the boxes should not
be open throughout this term unless urgently necessary.
Cured parts should be stored only packed.
NOTE: When sending the spares from depot, it is not recommended to violate the Supplier's
preservation. It is recommended to check the package contents against the Data Sheets which should
indicate the part TSos and their quantities in the package.
The engine preserved for one year may be stored unpackaging, covered with a tight fabric cover on
supports allowing external inspection and lubrication.
The supports should be made of wood with a moisture content of up to 18 % and painted at points of
contact with the engine. Besides, these points should be lined with paraffined paper.
Individual SPTA sets for the engine should be stored on supports so that the distance from the box
base to the floor is at least 400 mm.
It is strictly prohibited to keep any items directly on the floor.
When transporting from depots, the items should be protected against precipitation (snow, rain).
Systematic inspections should be carried out for the engine and spares kept in the storeroom.
The storeroom should have a special Register for recording the procedure and terms of inspection of
the engine and spares.Besides, each unit should have a tag reading the date of the last inspection and the
date of the next one as well as the name of person in charge of its condition and inspection.
All operations relating to the engine should be also entered into its Log Book, in addition to the
Register and tag.
When keeping the engine packaged for one-year storage, subject it to inspection once in six months
using the following procedure:
(a) Make sure through the spark plug holes that grease is present on the cylinder sleeves and there
is no corrosion.
(b) Make sure the airscrew shaft splines are free of corrosion.
(c) Remove covers from the exhaust ports and check condition of the valves.
When storing the engine packaged for 4-year storage, inspect it through the film every month
throughout the storage period.
If silica-gel indicator turns pink, proceed as follows:
(a) Cut the cover upper seams (near the edge) with scissors.
(b) Carefully roll out the cover.
(c) If the silica gel in cartridges is pink, drive out the cartridges and make sure the cylinder sleeves
are greased; use an electric lamp for the purpose.
Replace dehydrator cartridges with pinky silica-gel indicator with new cartridges loaded with blue
silica-gel indicator.
(d) If silica gel in the indicator or check cartridges turned pinky, replace all silica-gel dehydrator and
silica-gel indicator.
(e) Wrap with paraffined paper the engine parts that were wrapped originally with paper.
(f) Close the engine with the same cover, evacuate air and fuse it.
Never touch metal parts with ungloved hands. Never take the metal parts by painted or dressed
surfaces (chrome-plated, varnished or cadmium-plated, etc.). If this cannot be avoided, use knitted gloves or
appropriate appliances (tongs, etc.), oiled rags or tight paper (waxed, paraffined, etc.).
On expiration of every six months after original preservation, open the individual SPTA set boxes and
inspect the parts using the following procedure:
