Applies to Viscount Model 810 Series Aircraft. Compliance required as indicated. To prevent further failures of entrance doors during pressurized flight: (a) Within the next 250 landings after the effective date of this AD, accomplish the following: (1) Visually inspect the door locking mechanism of each entrance door in accordance with paragraph B.1 of Vickers-Armstrongs Preliminary Technical Leaflet No. 112, Issue 2. Repair any found defective before further flight. (2) Inspect for position accuracy the check markings applied to each claw and fuselage aperture. Where no such markings exist they must be applied in accordance with Figure 2 of PTL No. 112, Issue 2, or an FAA-approved equivalent. (b) Within the next 700 landings after the effective date of this AD, on aircraft fitted with airsteps or other installed equipment which obscures any claw from view, incorporate Vickers-Armstrongs Modification G.1964 (remote position visual indicator) or an FAA-approved equivalent. (c) Within the next 1,000 landings after the effective date of this AD, and thereafter at intervals not to exceed 1,000 landings from the last inspection, inspect the door locking mechanism of each entrance door for condition and correct operation, in accordance with paragraph C of P.T.L. No. 112, Issue 2. Repair any found defective before further flight. (d) For the purpose of complying with this AD, subject to acceptance by the assigned FAA maintenance inspector, the number of landings may be determined by dividing each aircraft's hours time in service by the operator's fleet average time from takeoff to landing for the aircraft type. (Vickers-Armstrongs Preliminary Technical Leaflet No. 112, Issue 2, dated August 6, 1964, (800-810 Series) and Modification G.1964 cover this subject.) This directive effective July 26, 1965. FOOTER:
