🛷**Diving Deep into the EH216-S Landing Gear DROP TEST!** 💡Ever wondered why this test is so crucial. It’s all about safety and performance of the landing gear system’s shock-absorption capabilities. We simulate both normal and emergency conditions, from everyday landings to instances of overweight or other hard landing scenarios,...

Why the 737 landing gear lever has an “OFF” position ✈️ It’s a question I get asked quite often and understandably so! “OFF” isn’t a logical position for the landing gear! The landing gear is retracted into the belly of the aircraft using hydraulic pressure. Once the gear is fully up, mechanical uplocks hold the gear safely in position. However, with the lever in the UP position, hydraulic pressure is still being applied to the system. This is unnecessary now that the gear is being held up with mechanical latches and places extra demand in the hydraulic pumps. So, once the gear has been retracted, the pilots will move the gear lever from UP to OFF as part of the after takeoff checklist. This simply removes hydraulic pressure from the retract lines. When the pilots configure the aircraft for landing, we move the landing gear lever from OFF to DOWN. This action releases the mechanical up locks and the gear is lowered using a combination of hydraulic pressure, gravity and air loads. Once the gear is fully down and locked, a green light - one for each set of wheels, will illuminate. Should the primary gear down sensors fail, we have a second set of green, gear down indicators on the overhead panel. As long as the gear is indicating down and locked on either the primary or standby indicator, the gear is down and locked and safe to land on 👍 In the very unlikely event that the gear won’t lower normally using the landing gear lever, we have a standby gear lowering system which allows the crew to manually release the gear uplocks and allow gravity to lower the gear - see my reel showing that system in operation .

Spoiler warning on why regulations are written in blood - the checklist debacle that caused one of Canada´s worst aircrashes was OTD, 56 years ago July 6 1970: Air Canada 621, a DC-8, crashes in Toronto (Canada), and all 109 aboard die. After a hard landing, the #4 engine and part of the wing fell. The crew was attempting a go-around when the jet exploded. The investigation pointed out issues with SOP related to the deployment of ground spoilers. More details on this accident below, which is a textbook example on “why” not to invent regarding SOP, in this case regarding lift spoilers, a device which is activated on landing to reduce lift and slow the aircraft. The crew of Air Canada 621 (Captain Hamilton and First Officer Rowland) had an informal arrangement to handle spoilers differently depending on who was flying, deviating from standard procedure. The landing flare reduces descent just before touchdown, and if spoilers are armed, they deploy automatically upon landing. Instead of arming them during the pre-landing checklist as required, the captain favored deploying them only after touchdown, while the co-pilot preferred doing so during the landing flare. Both procedures were unauthorized. During this flight, the captain was landing and asked for spoilers during the flare, which was unusual. The first officer mistakenly deployed them, instead of arming them, causing a sudden loss of lift. The aircraft hit the runway hard, damaging an engine and the wing, but managed to take off again for a go-around. However, fuel leaks ignited, leading to multiple explosions that destroyed the right wing. The aircraft went into an irrecoverable dive and impacted a field, killing all aboard instantly. As expected, the enquiry focused on crew actions. Eight recommendations were made, including redesigning the spoiler activation lever so it cannot be used during flight, strengthening the DC-8’s wings and fuel tanks, and updating Air Canada’s training and operating manuals to clearly define proper spoiler arming and deployment procedures.
