    Owning an aircraft of any kind is a serious investment, and one that demands top-tier care to keep it flying safely. Whether you’re a seasoned operator or new to the industry, it is important to keep up with landing gear maintenance requirements for your aircraft so you can avoid costly downtime and ensure peak performance.

    In this article, we’ll walk you through landing gear maintenance requirements for Challenger 300 and 600 series aircraft. From routine inspections to major overhauls, we’ll walk you through what it takes to keep your aircraft in the air where it belongs.

    What Goes Into A Landing Gear Inspection/Restoration Of A Challenger 300 Or 600 Series Aircraft?

    Before we dive into overhaul requirements for a Challenger 300 and 600 series aircraft, it is important to note that “restoration” and “overhaul” mean the same thing.

    For a Challenger 300 or 600 series aircraft, except the 601, a detailed inspection is due at the first 96-month mark and restoration at the first 192-month mark. After the initial 192-month restoration, restoration is due again every 96 months. For Challenger 601, the landing gear is due for a detailed inspection at the first 60-month mark. When the aircraft gets to the 120-month mark, it is due for restoration.

    Here are important inspection/restoration intervals for Challenger 300, 350, 604, 605, and 650 series aircraft:

    • 96-month detailed inspection
    • 192-month restoration (overhaul) 
    • Reoccurring restoration (overhaul) due each 96 months following the initial 192-month restoration

    And for Challenger 601 aircraft:

    • Reoccurring 60-month detailed inspection
    • Reoccurring 120-month restoration (overhaul)
    • Detailed inspections are mainly visual, with minor disassembly required; we focus our inspection on high corrosion/wear areas throughout the landing gear

    During a restoration/overhaul, the landing gear is completely disassembled and stripped down to bare metal. We perform visual, dimensional, and nondestructive inspections to locate any discrepancies with the landing gear.

    AAI Provides Maintenance & Overhaul Services On Challenger 300 & 600 Series Aircraft

    No task is insignificant when maintaining your aircraft components in a condition fit for flight.

    Detailed, thorough, and expert work is required to get the job done the right way. At AAI, we know your ultimate goal is to get your plane fixed so you can fly. That’s why we go above and beyond to help you avoid extra costs by creating repairs and manufacturing the parts on your aircraft that are prone to corrosion and wear, like landing gear components.

    Challenger maintenance and overhaul requires quick turnaround times. You don’t want a hangar full of planes propped up on jacks, creating a traffic jam for everyone trying to maneuver around them. AAI completes landing gear inspections and repairs in-house so that parts get turned around quickly, and you can return your aircraft to normal operation.
