INTRODUCTION

1-1. GENERAL.

WARNING

Unauthorized modification to, and devi-ations from prescribed life support and sur-vival equipment by individual aircrew-member could create unknown safety haz-ards. The OPNAVINST 3710.7 Series specifies minimum requirements for such equipment and is supplemented by the in-dividual model NATOPS.

1-2. COMNAVAIRFORINST 4790.2 identifies NAV- AIRSYSCOM as the only authority for modifications to life support and survival equipment, which is usual-ly accomplished by the Fleet Support Team (FST) (formerly Cognizant Field Activity (CFA)) via Aircrew Systems Changes or a change to the equipment pro-curement package. This manual also permits an oper-ating activity with approval of the controlling custo-dian, to conditionally modify ONE UNIT of equipment in-service to correct or overcome unsatisfactory condi-tions in that equipment item. Any other type of devi-ation/peculiar configuration or modification to life support and survival equipment is disallowed, and the Aircrew Survival Equipmentman has no authority or responsibility to perform them.

1-3. If an omission or conflict should occur between FST documents and NATOPS requirements, or if there is a need for clarification of equipment configuration or if equipment deficiencies are discovered, the appli-cable FST should be notified. If maintenance deficien-cies are discovered, they shall be reported to area type commander in accordance with COMNAVAIRFORINST

4790.2. The FST for most of the life support and

survival equipment is Commander, Naval Air Warfare Center Aircraft Division (NAWCAD), Attn: Code 4 . 6 . 7 . 4 , B l d g 2 1 8 7 , P a t u x e n t R i v e r , M D 20670-1906. For parachutes and related hardware, in-cluding torso harnesses, the FST is the Naval Air Warfare Center Weapons Division, Code 463000D, China Lake, CA 93555. NAWCAD DET Indianapolis, IN 46219 has cognizance over all survival radios and emergency beacons. NSWC, Indian Head, MD is FST for the FLU-8B/P Automatic Inflation Device.

2-16. GROUP ASSEMBLY PARTS LIST.

2-17. The Group Assembly Parts List (GAPL) contains illustrations and parts lists for each major assemb-

ly. These illustrations and accompanying lists show how the major assemblies are disassembled into subas-semblies and detail parts. Each item illustrated is indexed for identification purposes. Each illustration is accompanied by a parts list providing a part number, description, and quantity for each item. The list is arranged in disassembly order. Through the use of a system of indentation, the relationship of the detail parts to the subassemblies and the relationship of the subassemblies to the main assembly, is shown.

2-18. F IGURE AND INDEX NUMBER COL-

UMN. The figure and index number of each item shown on the corresponding illustration appears in the Figure and Index Number Column, with the exception of assemblies and subassemblies which are not illus-trated in assembled form. In these cases, the assem-blies or subassemblies are listed but not indexed. The component parts thereof are both listed and indexed.

2-19. PART NUMBER COLUMN. This column contains the contractor’s drawing number, government standard number, vendor drawing number or identifies the part as being commercial hardware (COML). Gov-ernment standard parts are listed using the applicable MS, AN, AF, NAS, MIL, or JAN part number. Where the part number is controlled by a military specifica-tion, this specification number is listed in the De-scription Column.

2-20. DESCRIPTION COLUMN. This column lists the item name plus those modifiers necessary to iden-tify the item. The description of a vendor-supplied

2-3 item includes a five-digit number which identifies the manufacturer. This is the Commercial and Govern-ment Entity (CAGE) code. To correlate this CAGE code to the manufacturer’s name, refer to the catalog-ing handbook H4/H8. CAGE codes may be omitted for prime manufacturer’s parts and for government standard parts. When applicable, contractor’s control drawing numbers and reference designations of elec-tronic parts are also listed for general reference.

When a separate exploded view is used to show the detail parts of an assembly or subassembly the De-scription Column contains an appropriate figure cross-reference in parenthesis fol lowing the descrip-tion. This cross-reference appears both in the listing where the assembly is first described, and in the list-ing which the assembly is broken down. In the latter case, the abbreviation REF will appear in the Units Per Assembly column. Commercial hardware items (COML) are fully described so that they may be pro-cured from normal commercial sources. Parts stocked in kits are identified with kit component code in this column, i.e., KD.

2-21. Indentation. The indentations headed “1” through “7” in the Description Column are provided to show the relationship of assemblies and their detail parts. The detail parts are indented one space to the right and listed below the assembly to which they belong. Determine the next higher assembly (NHA) of any detail part by locating, in the next space to the left (excluding attaching parts) the first item above the detailed part.

2-22. Attaching Parts. Attaching parts are items used to attach parts or assemblies to each other and follow immediately after the part to be attached. The attaching parts have the same indentation as the part attached. The caption “(ATTACHING PARTS)” is placed on the line immediately above the listing of attaching parts. The separation symbol ---*--- appears on the line immediately under the last attaching part. Quantities of attaching parts are listed per unit. For example, if two fittings are required for each assembly and one bolt is required to attach each fitting, the correct listing would be:

. FITTING ASSEMBLY, Hinge 2

(ATTACHING PARTS)

. BOLT 1

2-23. UNITS PER ASSEMBLY COLUMN. This column shows the quantity of an item required in the next higher assembly. The abbreviation AR indicates when the quantity is “As Required”.

2-24. USABLE ON CODE COLUMN. Usable on codes are used to indicate part usage where various models and serial numbers of the equipment or simi-lar parts within the equipment use different parts. A code is assigned to each variation of the equipment and entered into the GAPL when a part is used only in a specified variation. Where no code is entered, the part is used on all units covered by the GAPL or when no variations from the original equipment exist.

2-25. NUMERICAL INDEX.

2-26. The numerical index which follows each GAPL contains all the part numbers listed in that GAPL, arranged in alphabetical-numerical sequence.

2-27. PART NUMBER COLUMN. This column contains the part numbers of the parts and assem-blies. Part number arrangement starts at the extreme left-hand position and continues left to right, one position at a time, according to the following order or precedence:

Space (blank column) Diagonal (Slant) Point (period) Dash (hyphen) Letters A through Z Numerals 0 through 9

2-4

NOTE

Spaces, diagonals, points, and dashes do not appear in the extreme left-hand posi-tion of the part numbers. However, they may be used in the second and succeeding positions and take precedence over letters and numbers as indicated above.

2-28. F IGURE AND INDEX NUMBER COL-

UMN. In this column, the digits preceding the dash refer to the figure in which the parts are i l lus-trated. The digits following the dash are the index numbers.

2-29. SOURCE , MA INTENANCE AND RE-

COVERABILITY (SM&R) CODE COLUMN. The five digit SM&R codes, assigned by Naval Air Sys-tems Command Representatives are reflected in the SM&R code column. The code format is composed of three parts consisting of a two-position Source Code, a two-position Maintenance Code and a one-position Recoverability Code. See Table 2-1 for basic information.

NOTE

For more complete information on Uniform SM&R Codes, refer to NAVSUPINST 4423.29, OPNAVINST 4410.2A, and NAV-

CHAPTER 4

LR-1 LIFERAFT ASSEMBLY

Section 4-1. Description

4-1. GENERAL.

4-2. The LR-1 is a one-man liferaft utilized with various soft and hard type survival kits. It is intended for use by an aircrewmember forced down at sea. It can also be used when forced down over land for fording rivers and streams or as shelter. See Figure 4-1 through Figure 4-6.

4-3. CONFIGURATION.

4-4. The LR-1 liferaft assembly consists of a inflation assembly (CO2 cylinder and inflation valve) and a one-man liferaft constructed of polychloroprene-coated cloth. Three types of CO2 cylinders and one type of inflation valve, FLU-6/P or modified FLU-6/P is avai-lable. The liferaft consists of a single compartment flotation tube with a non-inflatable floor. It is blue in color and features a weathershield, sea anchor, sea anchor pocket, retaining line pocket, and ballast bags. The weathershield is nonspecular sea blue in color on the outside and bright red on the inside. The survival items which may be required in LR-1 liferaft assemblies are listed for reference only in Table 4-1, and most must be individually requisitioned.

4-5. APPLICATION.

4-6. The type of packaged LR-1 liferaft assembly used aboard various types of aircraft is shown in Table 4-2.

4-7. FUNCTION.

4-8. The LR-1 liferaft assembly is inflated either manually by pulling the inflation assembly actuating lanyard or automatically on LR-1 (RSSK) by gravity drop on kit actuation. The inflation assembly inflates the flotation tube. After boarding, the LR-1 may be topped off by using the oral inflation valve.
