BGA AIRWORTHINESS AND MAINTENANCE PROCEDURES PART 2, LEAFLET 2-8 COMPILATION OF CAA LOG BOOKS INTRODUCTION 1. All CAA (G-reg) Motor gliders and Tugs are required to have approved Log Books detailing aircraft information, flights, maintenance, inspections, modifications and compliance with mandatory directives. The CAA supplies suitable Log Books, each of which has an "Instructions for use" section. However descriptive information is also contained, in an easier to use format, CAP520 "Light Aircraft Maintenance". The aim of this leaflet is to provide readily available guidance on how these Log Books are to be compiled to ensure the proper control of continued airworthiness. Further guidance on the compilation of Log Books is contained in Civil Aircraft Airworthiness and Inspection Procedures, Leaflet 1-5. AIRFRAME LOG BOOK 2. The CAA Airframe Log Book is CAP398 and it has a Blue cover. The following information applies to Part A - White Pages - of the Log Book. See below for details of how to compile the coloured pages. The numbers apply to the column number on the page of the Log Book. 1. Date. Details of flights that day. 2. No of Flights. Unless your operation requires it or your airframe is flight cycle limited, it is not necessary to record the number of flights. 3. Flight time. Record the total for the day.* 4. Total since Manufacture. This is the cumulative total airframe time.* *The time may be recorded in Hours and minutes or Hours and decimal points ie 2h 45m or 2h 75 depending on how you calculate flight time. If you adopt decimal you must make a statement at the start of using decimals in column 6 (Decimal Hours) and vice-versa if you go back to hours and minutes. 5. Engine cycles. Only required if your engine TBO is cycle controlled. 6. Particulars of maintenance and other work. You should record maintenance checks and maintenance schedule (LAMS/A/1999/BGA issue 2). A record of any mandatory inspections, modifications etc. Record serial numbers of components taken off and put on, and the release number of parts used; the latter may be contained in a file provided a reference is made. Part or all of the entry could be made with a stamp if preferred. In addition, any "Pilot Maintenance" should be certified in this section. 7. Signature, Authority, Date. You should sign this section and enter your BGA Authorisation number and BGA Approval number (DAI/8378/73) or CAA licence number if appropriate. You may stamp your Authorisation number provided it is legible but not your signature. The date is the date of completion of the maintenance activity and release to service. The signature constitutes a legal statement and is a AMP 2-8/Nov 05 BGA AMP Part 2, Leaflet 2-8, Page 1 "Certificate of Release to Service". "Pilot maintenance" should not be certified in this section. (See leaflet 2-1 in this manual). ENGINE LOG BOOKS 3. The CAA Engine Log Book is CAP 399 and it has a Grey cover. The following information applies to Part A - White Pages - of the Log Book. See below how to compile the coloured pages. The numbers apply to the column number on the page of the Log Book. 1. Date. The entries in the engine log book may be grouped into blocks of a maximum of one week. If a maintenance check is performed, a block must end at that point. 2. Time run since New or Complete overhaul. The critical words here are NEW or COMPLETE OVERHAUL which mean ZERO houred. This is used for the engine TBO.* If a separate method of recording engine hours is available (Thaco counter or Hobbs meter) actual engine operating hours may be recorded for check cycle and TBO. In this case the Airframe and Engine hours may run out of sequence, and say, a 50 hour Airframe check will be due before the 50 hour Engine check. The check cycle must be realigned at the Annual inspection. 3. Time run since Top overhaul. This means the cylinders and heads have been OVERHAULED or NEW fitted. It does not mean repaired.* *As with the airframe log book you can use decimal hours. 4. Cycles run. Again this need only be completed if your engine's TBO is cycle controlled. 5. Particulars of maintenance. A similar entry to the airframe logbook but you should also add after the schedule ref. The cylinder compression test results if required for the particular check. As with airframe log book "Pilot maintenance" should be certified in this section. 6. As per airframe log book. VARIABLE PITCH PROPELLER LOG BOOK 4. The CAA Variable Pitch Propeller Log Book is CAP 400 and it has a Yellow cover. The entries are similar to the engine logbook, but it is not necessary to run a separate log book unless you have a constant speed propeller. For Motor Gliders only - You can run the details in the engine logbook provided you remember to transfer the details when you have an engine overhaul;. On tugs the propeller should be run in the airframe logbook as you are unlikely to fly the aircraft without the propeller operating. INFORMATION COMMON TO ALL LOG BOOKS 5. Part B - Green Pages. Enter details of check ie 50 hr/6mth, 150 hr, Annual, Star. Date certified, hours from new or zero hour overhaul in the case of an engine or propeller. 6. Part C - Pink Pages. First is a section to enter mandatory requirements not applicable to the aircraft, Engine or propeller. This is to assist conducting mandatory searches in the future. By column number, the date required is: AMP 2-8/Nov 05 BGA AMP Part 2, Leaflet 2-8, Page 2 1. Modifications, SBs & ADs. Enter the AD number ie FAA2005-00-00 or D-2005-001 in the mandatory section and Service bulletin number in the Non-mandatory section. 2. Subject ie Fuel selector. 3. Date & Hrs at Compliance. Date and hours the certification was made taken from Part A of the log book. 4. Method of compliance. As required in the instructions ie Inspection. Part 1 only or modified. 5. One time. Tick if the action performed completes the AD or SB and no further inspections or actions are required. 6. Recurring. Tick if any further action is required or it is a repetitive inspection. 7. Next compliance due. If you ticked column 6 then you have to enter the date and airframe or engine hours the inspection or action is next due. 8. Signature. This has to be signed with your approval or licence number and date. It is not however a certification. This is included in part A of the logbook. TIME LIMITED TASK AND COMPONENT CHANGE RECORD 7. The CAA Time Limited Task and Component Change record is CAP543 and it has a Blue cover. This document is essential for aircraft maintained to the CAA's Approved Maintenance Schedule CAA/LAMS/A 1999. The document is used to control the accomplishment of scheduled time-limited tasks and component changes. It can partly be used to replace the logbook Part C pink pages. If items are transferred to this document a reference should be made in part C of the logbook. CORRECTIONS OF LOG BOOK ENTRIES 7. Any errors should be drawn through with a single line (red if possible) initialled and dated. Corrector fluid (Tipp-ex) must not be used. There is no problem with errors provided they are corrected. If a flight time error occurs over a long period a correcting entry is required at the date it was found, duly certified. Do not correct all the previous entries. ANNEXES: A.
