Inspect the flap actuator switch to determine if switch P/N NOR 7-345-4 (Honeywell Product P/N 13AT3) is fitted to the aircraft.\n\n    2. Remove the above flap switch if fitted.\n\n    3. The original flap switch P/N NOR 7-345-1/M may be refitted provided that the rubber ring is installed and the knob adjusted for a 4mm gap between the edge of the mounting bushing and the base of the knob; or\n\nan equivalent switch approved by the Secretary may be installed.\n\nNote: A switch installation in accordance with Drawing No. EDS 140 supplied by Forrestair is an acceptable means of compliance.\n\nCompliance: Before 31 March 1980.\n\nNote: Compliance with the original AD/P68/17 does not constitute compliance with this AD/P68/17A.\n\nBackground: The new flap switch which Partenavia SB No. 46 called up (P/N NOR 7-345- 4/Honeywell P/N 13AT3) has proved to be electrically inadequate and at least two open circuit micro switches have been reported. The manufacturer’s rating of the switch is 3 amps inductive load at 30V DC and the flap motor draws up to 6 amps. If the original switch has the rubber ring fitted correctly it should be satisfactory for operational use and the switch is more than adequate electrically.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2808},"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":true,"description":"This amendment significantly alters the original directive's scope. The original AD/P68/17 apparently mandated or accepted the installation of the now-faulty switch (P/N NOR 7-345-4). Amendment 1 reverses this requirement, mandating the removal of that specific switch and providing detailed technical specifications for reinstalling the original component or approved alternatives. It explicitly invalidates compliance with the original directive, effectively narrowing the scope to specific corrective actions."},"complexity_factors":["Multiple specific part numbers requiring precise identification (NOR 7-345-4, Honeywell 13AT3, NOR 7-345-1/M)","Technical installation measurement requirement (4mm gap specification)","Dual alternative compliance pathways (original switch refit vs. Secretary-approved equivalent)","Reference to external technical documentation (Drawing EDS 140, Service Bulletin No. 46)","Explicit non-recognition of prior compliance creating overlapping obligations"],"plain_english_summary":"This mandatory safety directive orders all Partenavia P68 owners/operators to inspect for and immediately remove the faulty flap actuator switch (NOR 7-345-4 / Honeywell 13AT3). The switch is electrically undersized (3 A vs the flap motor’s 6 A), has failed in service, and risks flap-system malfunction. Replace with NOR 7-345-1/M fitted with the specified rubber ring and a 4 mm knob gap, or with a Secretary-approved equivalent; Forrestair Drawing EDS 140 is pre‑approved.
