1                                 General

1.1                           Introduction

The aircraft and/or equipment Topic 2 deals with Design Organization modifications.  However, there are instances where 4Project Teams (PTs)3 need to promulgate specific information relating to their aircraft and/or equipment.  The Topic 2(N/A/R) series – General Orders, Special Instructions and Service Modifications, is a tri-Service publication, which provides the means for 4PTs3 to publish their aircraft and/or equipment-specific orders, special instructions and modifications.  Additionally, the JAP 100A-01 chapters listed in Table 1 require 4PTs3 to include specific information in the Topic 2(N/A/R).

1.2                           Associated instructions

This chapter is associated with the following instructions:

1            AP 100C-20 – Preparation and Amendment of Maintenance Schedules.

2            Acquisition Operating Framework (AOF)

3            DAvP 70 – Specification for Air Technical Publications.

4            JSP(D) 543 – Defence Technical Documentation - Policy & Requirements

1.3                           Definitions

The designators (N/A/R) denote the applicability of the publication with regard to each of the 3 services, where N is for the Royal Navy, A is for the Army and R is for the Royal Air Force.  This identifies that the General Orders, Special Instructions and Modifications have been authorized for aircraft and/or equipment used by the respective Service.  Thus a Topic 2(A/R) indicates that this Topic 2 is authorized for aircraft and/or equipments used by the Army and the RAF, whilst a Topic 2(A) indicates that the Topic 2 is authorized for aircraft and/or equipment used only by the Army.

2                                 Policy on Topic 2(N/A/R) – General Orders, Special Instructions and Modifications

All aircraft 4PTs3 are to promulgate a Topic 2(N/A/R).  Where an aircraft type has more than one mark, 4PTs3 may adopt single all-marks Topic 2(N/A/R) or produce a Topic 2(N/A/R) for each individual mark of aircraft.  A suggested layout is contained in this chapter. 

Equipment 4PTs3 are to use the Topic 2(N/A/R) series as described in this chapter.  However, where it is more cost-effective to do so, they may publish their General Orders, Special Instructions and Modifications in the relevant aircraft Topic 2(N/A/R), following agreement with the appropriate aircraft 4PT3.

FLCs, with the agreement of the relevant 4PT3, may publish aircraft and/or equipment-specific information within the relevant Topic 2(N/A/R).

3                                 Layout of Topic 2(N/A/R)

The following paragraphs detail a suggested layout for the for the Topic 2(N/A/R) series of publications.  The aircraft and/or equipment 4PT3 may change this layout to meet specific requirements; however, it must contain the detail described in this chapter.  The layout for each Topic 2(N/A/R) is to be stated in the aircraft and/or equipment Support Policy Statement (SPS).  The Topic 2(N/A/R) is sub-divided into the following sub-topics:

1            Topic 2(N/A/R)1 – General Orders and Special Instructions.

2            Topic 2(N/A/R)2 – Service Modifications (SM).

3            Topic 2(N/A/R)3 – Service Engineered Aircraft Radio Installation Modifications (SRIMs) (obsolete).

4            Topic 2(N/A/R)4 – Special Trial Fits (STF) (obsolete).

Topics 2(N/A/R)2, 3 and 4 need only be published for aircraft, equipment and omnibus ranges for which SMs, SRIMs or STFs have been issued.

3.1                           Topic 2(N/A/R)1 – General Orders and Special Instructions

The Topic 2(N/A/R)1 is divided into a minimum of 3 parts, each with its own index of individually numbered leaflets.

3.1.1                        Part 1 – General Orders

The first leaflet of Part 1 in the Topic 2(N/A/R)1 is to be the SPS for the aircraft and/or equipment.  The remaining leaflets are to be numbered sequentially and contain those instructions required by the 4PT3.

3.1.2                        Part 2 – Locally Manufactured Equipment (LME)

Instructions dealing with LME unique to an aircraft, equipment or omnibus range are to be contained in Part 2.  4Note: see Chapter 6.3 for LME policy.3

3.1.3                        Part 3 – Special Instructions (Technical)

Part 3 is to be sub-divided into the following sections:

1            Special Technical Instructions.

2            Servicing Instructions.

3            Urgent Technical Instructions.

4            Routine Technical Instructions.

Each section is to include an index that lists, by reference number and title, all instructions issued for the aircraft, equipment or omnibus range, with details of amendment, fleet/equipment range embodiment, supersession or cancellation, as appropriate.  Copies of current instructions are to be placed and held in the respective section.  If copies of closed instructions are retained in these sections for record purposes, they are to be annotated ‘CLOSED’ to identify their status.

SI(T) produced as hard copy for inclusion into the Topic 2(N/A/R) is to comply with the format standards specified in JSP 182.

The section indexes are to be re-issued as necessary in order to keep to a minimum the number of manuscript entries generated by the issue, amendment and withdrawal of instructions.

3.2                           Topic 2(N/A/R)2 – Service Modifications (SMs)

The contents list of this sub-topic is to be an index of all SMs raised for that aircraft, equipment or omnibus range, with details of amendment, fleet/equipment range embodiment, supersession and/or cancellation, as appropriate.  Current SMs in course of fleet/equipment range embodiment are to form the subsequent leaflets, with the leaflet numbers equating to the SM number.

3.3                           Topic 2(N/A/R)3 – Service Engineered Aircraft Radio Installation Modifications (SRIMs) (Obsolete)

Legacy SRIM leaflets were published in this sub-topic, together with an index of all published SRIMs, in a similar format to that for the Topic 2(N/A/R)2.  Note that no new SRIMs are to be developed, as the procedure has been superseded by the SM procedure; see Chapter 10.4.

3.4                           Topic 2(N/A/R)4 – Special Trial Fits (STFs) (Obsolete)

The contents list to this sub-topic is to list all legacy STFs issued for the aircraft or equipment type and include details of their amendment, removal and cancellation.  If copies of cancelled STFs are retained in this section for record purposes, they are to be annotated ‘cancelled’ to identify their status.  Note that no new STFs are to be developed, as the procedure has been superseded by the SM procedure; see Chapter 10.4.

3.5                           Additional Topic 2(N/A/R) sub-topics

4A PT 3may decide that there is a requirement for additional sub-topics within its Topic 2(N/A/R) system.  If they are used, the requirement is to be published in the SPS.  Each new sub-topic is to have its own appropriately structured index and individually numbered leaflets.

4                                 Omnibus topics

Aircraft and/or equipment 4PTs3 will normally publish a discrete Topic 2(N/A/R); however, it may be more appropriate to publish an omnibus Topic 2(N/A/R) for a range of equipments when a discrete topic cannot be justified economically.

5                                 Publication and amendment action

4PTs3 are to publish their own Topic 2(N/A/R).  Amendment proposals are to be forwarded to 4PTs3 on MOD F765.

6                                 4Project Team (PT)3 responsibilities

4PTs3 are responsible for:

1            The content, production and through-life management of their Topic 2(N/A/R) series.

2            Carrying out an annual review of the content of their Topic 2(N/A/R) series to ensure that the information contained is current and up-to-date.
