PREVENTING FALLS FROM HEIGHT FROM, OR WHEN OPENING OR CLOSING
AIRCRAFT DOORS
This SIM provides guidance for inspectors on procedures and safe systems of work for
opening aircraft doors, and for avoiding falls from aircraft doors when open. The guidance
does not apply to cargo and hold doors.
INTRODUCTION
1 Falls from height are a significant risk at airports with 69 reported incidents under SIC codes
63230 and 62100 etc (Standard Industrial Classification codes for scheduled and nonscheduled
air transport and supporting activities) in 2002/03. In addition to those accidents
coded under these SIC codes HSE is aware of significant numbers of falls from maintenance
platforms, from catering high loaders, from passenger access steps, and from open aircraft
doors when steps have been either absent or withdrawn without warning, which may be coded
under different SIC codes not attributed directly to airport activities, or involve cabin or flight
crew and are reportable to, and may be investigated by, the Air Accident Investigation Branch
(AAIB).
2 Risks arise during maintenance of aircraft and during servicing and turnaround activities.
Specific guidance on safe access to aircraft during maintenance is in SIM 05/2002/52;
guidance on safe access for catering activities and use of high loaders is in SIM 05/2004/13.
3 Risks to ground handlers and aircraft crew have been identified during opening of the aircraft
door, when the door must be cracked and then opened, sometimes swinging out from the

SIM 05/2005/05 - Preventing Falls from Height from, or When Opening or Closing Aircraft Doors
aircraft body. A detailed description of this process and the risks arising when an operative has
to lean out from an unguarded high loader platform or steps can be found in SIM 05/2004/13.
4 While there are obvious risks in opening aircraft doors from the outside, there are also risks
in opening the doors from the inside. These include serious risks of injury if the emergency
chute is accidentally activated, and falling from an unguarded door if there is no ground
support equipment in place.
5 All Ground Support Equipment (GSE) should be designed in accordance with BS EN 1915 -
1:2001 Aircraft GSE - General safety requirements Part1: Basic safety requirements, and the
relevant parts of BS EN 12312 - Specific requirements. Safety features and proposed systems
of work should be considered at the design stage to ensure that access equipment reduces the
risk of falls so far as is reasonably practicable.
6 Procedures and responsibilities for opening and closing aircraft doors often rely on
cooperation and coordination between airline crew and ground handlers and should be
included in the Turnround Plan and monitored by the Turnround Coordinator or Supervisor.
7 Note: Terminology and definitions in this guidance are as detailed in the new Work at
Height Regulations 2005.
GENERAL PRINCIPLES
8 Inspectors should be aware of existing industry guidance on opening aircraft doors:
● CAA publication CAP642 (available on the CAA website) Chapter 2 para 8.2.2 states
that `Proper planning, safe systems of work and instruction and training are required to
ensure that aircraft doors are opened in such a way that no one is exposed to the risk of
a fall and the risk of damage to the aircraft is minimised ` and para 8.2.3 ` Airlines
