Applies to Model Lake LA-4 Aircraft.

Compliance required within the next 25 hours' time in service after the effective date of this AD unless already accomplished.

To prevent failure of the nose landing gear to latch in the down and locked position, accomplish the following:

  (a) Inspect the bolt at the top of the nose gear drag strut at Fuselage Station 12 5/8 that connects the upper drag strut assembly, Lake P/N 2-4411-1, to the support assembly plates, Lake P/N 2-4412-27, to ensure that an AN5-16A bolt or an FAA-approved equivalent is installed and that the bolt head is on the right-hand side of the aircraft.

  (b) If an AN5-15A bolt is installed, remove the bolt and visually inspect the bolt hole of the upper drag strut assembly and both support assembly plates for elongation.

  (c) Rework any part having an elongated bolt hole in accordance with Consolidated Aeronautics, Inc., Lake Aircraft Division, Service Letter No. 11B, dated February 22, 1965, or an equivalent approved by the Chief, Engineering and Manufacturing Branch, FAA Eastern Region, or replace the part with a new part of the same part number or an equivalent approved by the Chief, Engineering and Manufacturing Branch, FAA Eastern Region.

  (d) Replace any AN5-15A bolt with an AN5-16A bolt or an AN5-17A bolt as necessary when bushings are installed or an FAA-approved equivalent, installing the bolt with the head on the right-hand side of the aircraft.

  (e) Reverse any AN5-16A bolt that is installed with the head on the left-hand side of the aircraft.
