Airworthiness Compendium
Compendium of Airworthiness Directives, Mandatory Modifications, special Inspections and Check List of
Defects
Foreword and instructions for use
The lay out of the compendium is now listed under aircraft manufacturers name and is in a format to allow more
room for detail and reference information. Where two manufacturers make one type a cross reference is made.
From 2002 each entry will have a status as follows:
M
R
O
I
Mandatory for aircraft with a BGA or CAA C of A
Recommended by the BGA or manufacturer
Optional (usually modifications)
For information (usually guidance for inspectors or general information)
To research a particular aircraft look under the following:

Special inspections – All types
Tug and Motor glider issues (if applicable)

BGA Compendium 01/02
General information
COMPILED FROM: Airworthiness Directives (ADs), Service Bulletins (SBs), Tech Notes (TNs), Technical Instructions (TIs), Defect Reports, CAA Mandatory
Modification and Inspection Summary, CAA Airworthiness Directives Vol. 1 & 2, CAA Foreign ADs Vol. III. etc. Also experiences by BGA inspectors and
operators.
TUG’s The BGA compendium does NOT cover Glider Tug aircraft. Reference should be made to the applicable Airworthiness publications and manufacturers
information.
UPDATED: by BGA Technical News Sheets (TNS) - bi-monthly. From 2002 the TNS number will be aligned with the compendium. I.e. 01/02/02 will become
02/02, 03/04/02 will become 04/02, 05/06/02 will become 06/02 and on. Indicating month and year of publication
COMPLIANCE: - Unless stated otherwise, the AD’s listed in this compendium are mandatory for BGA registered gliders and Motor Gliders.
Notes:
1 AD’s are issued by National Airworthiness Authorities, generally to make manufacturers’ SB’s, TI's or Mods mandatory and to state time limits as to when
they must be carried out.
2 Items marked ”M” have been reviewed by the BGA and must be carried out as specified and entered in the log book Mods or Pink Pages section.
3 All other entries listed in this compendium are for guidance to aid inspections, and it is recommended that they are carried out annually, i.e. at C of A,
except when stated otherwise. From 2002 all entries will have a status indicator to assist inspectors to interpret the requirements.
CLUB TECHNICAL OFFICERS are asked to make all relevant airworthiness information available to club members and private owners.
CLUB COMMITTEES are reminded of their corporate responsibility to maintain high standards of airworthiness.
BGA INSPECTORS are required to keep a record of their work, such as copies of 267 forms or a diary.
CAA AIRWORTHINESS NOTICES detail repair and operational procedures for light aircraft, of which much is also applicable to gliders, is available from: Documedia Ltd, 37 Windsor St, Cheltenham, Glos, GL52 2DG tel. 01242 235151. Also available on the Internet [www.srg.caa.co.uk]
JAA PUBLICATIONS Copies of JAR22 and other JAA publications are available from Rapidoc, Willoughby Road, Bracknell, Berkshire, RG12 8DW. Tel.
01344 861666.
FURTHER INFORMATION The LBA publish AD’s on the Internet [www.lba.de] also many manufacturers have their own web sites (see contacts) were Tech
Notes can be downloaded. There are many more Tech Notes than listed in the Compendium; these are mainly for optional modifications. For details either
contact the agent or manufacturer direct.
ERRORS Please notify the BGA, in writing by letter or e-mail if any errors are found in this publication. [[email protected]]

Special Inspections All Types
General information for guidance of inspectors collated from Airworthiness Directives applicable to all types, experience of incidents, published articles and general information.
Note: Deleted entries in this section have been entered into relevant sections within the compendium. (Aircraft manufacturers, Engine, Propeller or Equipment)
1.
AIRBRAKES after repairs & repaints check opening & locking with wings bent. Insufficient clearance around paddle ends can prevent them being opened in flight.
TNS 06/96
2.
BALLAST WEIGHTS (& BAGS etc) must be secured. For preference use bolted in ballast weights. Record if ballast weights are fitted, especially if out of sight. TNS
12/00
3.
BGA FORMS 267 - to be signed for each item listed. “Mandatory Mods & Inspections” (Item 53). Compliance with this compendium & current TNSs must be checked
and entered in log books
4.
BUNGEE HOOKS should be removed to prevent hang-ups on cable parachutes.
5.
CABLES - is the swaging satisfactory? Hemp cored cables must be replaced. Ref TNS 08/93.
Stainless steel for control cables not recommended in applications with high chafing or tight turns on small pulleys. It has very poor fatigue properties. TNS 06/91,
Piper SB 1048 Lubrication of SS control cables.
6.
Assess the need for end-to-end inspections at annual check TNS 08/00
7.
CANOPY LOCK AND JETTISON SYSTEMS -inspect at every DI. Test jettisons annually.
8.
CONTROL SURFACE TAPE must be renewed regularly. Loose tape can cause major control problems. TNS 12/97 & 06/99. BGA inspection 011/12/2000 issue 1
detailing annual inspections on control tape and seals. TNS 12/00
9.
CONTROL RODS - can be damaged by root ribs during trailer transport. Secure them.
10. CONTROLS L’Hotellier connectors MANDATORY inspections LBA AD 1993-001/3 and AD 1994-001/2 applicable to all types
11. GROUND LOOPING INCIDENTS- inspections in depth are required to establish the integrity of both structures and control systems. Ref BGA GRP Inspection
Guidelines in Technical Procedure Manual.
12. INSTRUMENTATION TUBING - PVC loosens with age & leaks, glue it or use neoprene.
13. INSTRUMENT PANEL sharp metal edges are very dangerous. Leg protection must be fitted. Glass-fibre panels are much safer. “ASW” glass panels are designed to
break up during an accident. Instrument installations (compasses) impeding canopy jettison BGA 021/10/2001 iss1 recommended inspection.
14. LIGHTNING STRIKE inspections of GRP gliders. TNS 12/88 & wooden glider control cables TNS 04/87. The need for bonding is emphasised TNS 08/00.
15. LIMITATIONS - must be permanently and legibly placarded, (including engine limitations).
