INTRODUCTION

1. The requirement to operate Army aircraft with armament systems and fitted with Explosive Ordnance (EO) in the field demands unique maintenance management requirements.

2. This annex supplements the information provided in, and is to be read in conjunction with Section 3 Chapter 10—Management of Aircraft Explosive Ordnance Maintenance.

ARMY EO MANAGEMENT RESPONSIBILITIES

Commanding Officer

3. The Approved Maintenance Organisation (AMO) must have a formal and effective management structure for dealing with all armament and EO matters. This management structure incorporates all procedures and regulatory requirements including Standing Instructions (SIs) and Standard Operating Procedures (SOPs).

Senior Maintenance Manager

4. The Senior Maintenance Manager (SMM) or delegate is responsible to the CO for the management, authorisation, certification, and currency of all personnel who handle EO and conduct maintenance on any armament aircraft system for, or on behalf of the AMO.

Armament Engineer

5. The Armament Engineer (ArmE) is responsible to the SMM for:

  1. the management and integrity of aircraft armament engineering matters
  2. implementing approved armament policies, procedures and safety instructions for on aircraft maintenance
  3. coordinating EO emergency procedures for aircraft accidents and incidents.

Ammunition Technical Officer/Ammunition Technician

6. The Ammunition Technical Officer (ATO)/Ammunition Technician (AT) is responsible to the CO for implementing approved armament policies, procedures and safety instructions for storage, handling, use and transport of EO. The ATO/AT is specifically responsible for:

  1. the safe and effective management of EO issued to the AMO
  2. ensuring EO activities comply with applicable Explosive Safety Regulations
  3. provision, storage and safe custody of EO within their respective Bases and on deployment
  4. off aircraft EO emergency procedures.

Line Safety Controller

7. The Line Safety Controller LSC is to be appointed from suitability qualified personnel (minimum rank of SGT) who are then authorised to independently monitor all safety aspects relating to the loading or unloading of EO, to or from an aircraft. Stores loading operations are to be carried out under the control of a LSC whenever an explosive hazard safety concern may exist.

8. While there is no requirement for the LSC to be a technical tradesman, only personnel who are qualified and current on the weapon system may be appointed as a LSC. To achieve this authorisation, personnel are to demonstrate to the SMM or delegate a complete knowledge and understanding of all procedures and hazards involved in loading and unloading armament operations.

9. Prior to commencing EO operations, the LSC is to ensure the following instructions are observed:

  1. The Explosive Ordnance Loading Area (EOLA)/Forward Arming and Refuelling Point (FARP) is licensed and authorised for the type of EO to be loaded or unloaded.
  2. ‘ARMED AIRCRAFT’ signs and a sentry are in place at all vehicular entrances to the EOLA.
  3. ‘ARMED AIRCRAFT’ signs are clearly visible in the cockpit and all entrances to the aircraft.
  4. Aircraft are correctly bonded/earthed.
  5. All armament control systems are selected to ‘SAFE’ in accordance with authorised maintenance data eg all armament switches are ‘OFF’, ‘SAFE’ or ‘GUARDED’.
  6. An initial safety briefing is given to all personnel involved in EO operations.
  7. NO loading or unloading procedures are carried out simultaneously with refuelling/defueling operations on an individual aircraft.
  8. NO electrical power or hydraulic supplies are connected to the aircraft during loading, unloading of EO.
  9. A method to indicate the armed status of an aircraft is to be clearly visible to all personnel during day and night operations. A red indicator identifies a loaded aircraft and a green indicator indicates a safe (unloaded and safe) aircraft within the EOLA.
  10. Radio Frequency Hazards (RADHAZ) precautions are observed when loading/unloading EO containing Electro Explosive Devices (EEDs).
  11. Aircraft which have forward or side firing weapons are oriented in a direction such that the line of fire cannot cause injury to personnel or damage equipment, if inadvertently activated.
