A firm landing can rattle more than your nerves. Even if it felt fine in the moment, your landing gear just absorbed a lot of energy in a split second. Every builder asks the same question afterward: did I break something? A focused inspection will usually give you the answer. Here’s what to check during your next round of airplane maintenance so you can catch problems early and keep flying with confidence.
When your aircraft touches down harder than expected, that impact energy has to go somewhere. Most of it passes through the landing gear and into the surrounding structure: the mounts, bulkheads, and skin panels that hold everything together. That force doesn’t always leave a mark you can see.
Visible damage, like a bent strut or a cracked fairing, is easy to spot. Hidden damage is not. A gear leg can look completely normal and still have absorbed enough stress to weaken the metal underneath the surface. That’s why a quick glance isn’t enough after a firm landing.
This is part of why the material your landing gear components are built from matter. Aluminum, steel, and composite gear legs each handle impact stress differently, and knowing what you’re working with helps you know what to look for.
Post-landing inspections also tie directly into long-term airworthiness. If you’re flying under a special airworthiness certificate, staying on top of this kind of check is part of keeping your aircraft compliant. Catching small signs of stress now can stop structural fatigue from building up over time and turning into a real gear failure later. It’s a routine part of aircraft maintenance that protects both your plane and your safety record.
Matco ALS has manufactured wheels, brakes, and landing gear components for experimental aircraft in the U.S. for nearly four decades. That kind of hands-on manufacturing experience is exactly why we know what stress on landing gear actually looks like, and what builders should be watching for after a hard landing.
One quick note: the strut and gear leg assembly itself isn’t a part we manufacture. If you spot a bend, crack, or corrosion there, contact the strut manufacturer directly rather than trying to diagnose it yourself. Here’s what you can inspect on your own:
If your inspection turns up wear, damage, or signs of stress, you have a few paths forward. Minor issues, like a small stress crack caught early, can sometimes be repaired and monitored. More serious damage, like a leaking strut or a bent gear leg, usually means it’s time to have that component replaced rather than risk it failing in flight.
If you’re replacing gear, it’s a good opportunity to reconsider your setup. Our breakdown of shock-absorbing landing gear materials compares your options for durability, so you can choose gear built to handle firm landings better going forward.
A firm landing doesn’t have to mean a damaged aircraft, but it does mean it’s time to look closely. Checking for stress cracks, strut leaks, misalignment, and tire wear after any hard landing keeps small issues from turning into bigger ones. If your inspection turns up a worn tire, a tired brake, or a related landing gear component that’s seen better days, shop Matco ALS for landing gear components built for long-term reliability.
