No. 1 of the year 1937.

D.H.82 (TIGER MOTH") AEROPLANES: MODIFICATION TO MAIN PLANE STRUCTURE

1. Details of a modification to the attachment fittings at the root end of the top rear spar, Part No. H. 34746/7, on D.H. 82 ("Tiger Moth') aeroplanes, are given in de Havilland Technical News Sheet No. 203. Owners of such aeroplanes, or ground engineers concerned with their maintenance, should apply to The de Havilland Aircraft Company, Limited, Hatfield Aerodrome, Herts, for a copy of this publication.

2. An immediate inspection of the above-mentioned parts must be carried out, attention being directed to cracks in the portion bent to form the eye for the attachment pin. This part of the fitting can be exposed by opening up the fabric over the extreme root end of the top rear outer spar. Repeat inspections must be made every 25 flying hours until modified fittings are available. If defects are found, the aeroplane must not be flown until replacement fittings to Part No. H. 34746/7, Issue 6, are fitted.

3. Certificates of Airworthiness of the aeroplanes con- cerned will be liable to suspension or cancellation if the modification has not been effected within 4 months from the date of this Notice. Certificates of Airworthiness will not be renewed and ground engineers must not sign Daily Certificates of Safety for Flight in respect of such aeroplanes after the expiration of the afore-mentioned period unless the modifica- tion has been correctly embodied.
