(e) Reason This AD was prompted by reports of a cracked main fitting and sliding tube during overhaul of NLGs. We are issuing this AD to detect and correct cracks, defects, or damage of the main fitting and sliding tube of the NLG, which could result in failure of the main fitting or sliding tube, and consequent NLG collapse. (f) Compliance You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. (g) Detailed Inspection and Corrective Actions Within 900 flight hours after the effective date of this AD: Do a detailed inspection of the NLG main fitting and sliding tube for any cracks, defects, and damage of the paint or surface protection, including paint removal and cracking of the surface treatment. Before further flight after doing the detailed inspection of the NLG, remove the labels, paint, surface protection coatings, and cadmium from the NLG main fitting; do a detailed inspection for any damage to the surface that will impair the magnetic particle inspection (MPI); and, if any defects are found, before further flight remove any defects by polishing.
