    New NLG Service Bulletins Summary

    ICON released three Service Bulletins last week related to the Nose Landing Gear uncommanded retractions. It took me a little while to sort them out.

    SB-012624-A NLG Limit Switch Over-Engagement (Mandatory)
    This SB provides updated rigging instructions and design improvements for the new Retrofit Limit Switches that came out in October 2023 (SB-080323). If you don't have the new Limit Switch this is not required. An inspection is due within 5 runway landings; if the inspection passes the repair can be deferred to next condition inspection.

    SB-032420-C Recurring Inspection of Nose Landing Gear (NLG) Actuator Rigging
    This inspection is now due every 50 hr or 6 months (whichever comes first), instead of every 100 hr or annual condition inspection. The inspection is not required if either SB-080323 or SB-012724 (NLG Limit Switch Retrofit) have been completed.

    SB-012724 NLG Limit Switch Retrofit
    This is a new version of the NLG Limit Switch Retrofit SB (mechanical limit switches with long arms). It replaces SB-080323 and incorporates the updated rigging instructions and a design improvements included in SB-012624-A. You don't need to do this if you have already done SB-080323 (instead you do SB-012624-A). It is due at the next service interval. Once you perform this SB, you don't need to do the recurring Inspection required by SB-032420-C.

    Thanks for sorting this out. My annual is this week and I do NOT have the new switches so I will report back on how it goes. I am hoping I get my new Prop/VGs as well. More to come!
