The Advanced Concept Ejection Seat, or ACES II, is a gadget designed to store an aircrew at a moment’s observe. Otherwise known as the “remaining risk for existence,” the seat is the remaining wish an aircrew has in terms of surviving a surprising failure. When the time comes, they need to have complete faith in the machine and the properly-trained group of airmen who preserve it.
“It’s all approximately preventative upkeep,” stated Air Force Tech. Sgt. Keith Percy, an egress structures craftsman with the twenty-eighth Maintenance Squadron here. “We need to be on the pinnacle of it because we can’t test the device. Everything that we do needs to be best — the whole lot.”
The team of airmen makes certain this in the course of an egress final inspection, that is required every 30 days. During the inspection, the technicians perform a complete diagnostic of the gadget, check for any broken additives and switch out expired time-changeable items to make sure the plane is ideal to go.

“On every seat, we have some of the time-changeable items with the intention to expire if no longer swapped out, such as explosives, awful actuators, load resters, survival kits, etc.,” said Tech. Sgt. Mathew Wagner, an egress systems craftsman with the 28th Maintenance Squadron.
When improved via a fleet of approximately 25 B-1Lancer bomber aircraft, the workload gets quite huge. Aside from the explosive traces all through the cockpit, the crew of airmen needs to inspect for any and all matters that would cause a gadget failure, together with frayed parachutes, vintage or nonresponsive device and corrosion. Then, after replacing the faulty system, the airmen need to make sure the ejection device is nicely seated into the plane.
Wagner said egress is a hugely essential a part of an aircraft’s operability. With no room for error, the group ought to be on their toes and hyperaware of their repairs always.
“We can’t find the money for to make errors,” he said. “I’m now not saying our renovation is extra vital than anyone else’s, however wherein they can take a look at their structures to ensure they did it effectively, we can’t.”
Because the ACES II is a one-and-done mechanism, egress technicians ought to placed their coronary heart and soul into retaining it.
“I’ve skilled ejections within the beyond, and the first aspect that is going thru your head — the first factor you ask — is, ‘Did they make it via,” Percy said. “Job delight comes from making sure the pilots are safe and we did our jobs nicely, but I could go my whole profession without every other ejection happening.”
Although ejections are not often seen, aircrews can relaxation clean knowing the egress groups’ skill and willpower assist make certain their safe return whilst met with a worst-case scenario.
“That’s why this section is constantly below the squadron’s microscope,” Wagner stated. “We are the closing system within the aircraft that needs to work – the final line between existence and loss of life for the aircrew. It’s critical the seat works nicely so those aviators can come domestically to their families and fly any other day.”
Preparing for egress (break out) from a ditched plane takes some exercise, instead, it’s from a land ditching or a water ditching. As an Aviation Survivalman with the U.S. Coast Guard, one in every one of my many roles was to perform or instruct egress training in both the constant wing and rotor-winged aircraft.
Over the years (twenty plus), I began including extraordinary eventualities to my training curriculum that I felt could help to now not handiest preserve the (bi-annual) training from being redundant and dull, but might add a different angle to my trainees. In other words, the ordinary schooling locations the participant in his assigned flying role with a blindfold. When the teacher yells egress, each person gets rid of their seat belts, then the usage of a give up hand craw alongside the bulkhead, they find their manner to the closest go out and leave the aircraft. The egress schooling is then signed off and again to the shops they pass.
One year whilst doing water ditch egress education on a C-one hundred thirty, I decided to exchange things up a chunk. I made the primary run quite simple. I had them strap in without a blindfold and smacked the 245 bulkheads loudly with my palm and yelled, you simply hit the water! As they were educated to do for years, they at once released their seat belts and began their surrender hand craw towards their go out, and stepped out directly to the hanger deck searching out the signal-off sheet. “Not so short men. Everyone lower back inside and let’s do that with the blindfold on”. At this point, everybody is thinking, this ought to be a breeze. Once everybody become strapped in and blindfolded, I had my assistants alternate a few configurations within the plane. One unique alternate became to block the number one exits and permitting handiest one go out point, the left paratroop door in the again of the plane. But it get’s higher. I rotated the cope with that opens the paratroop door to the open function. In other words, they best needed to carry up on the door to open it. Oh, and did I point out the twelve roll seat pallet that changed into located inside the center of the cargo compartment?
Once everyone turned into again in function and strapped in, I slapped the bulkhead and yelled, you simply hit the water. As I suspected, all of them launched from the harnesses and started their surrender hand craw along the bulkhead. Bang! I slapped the bulkhead a second time and yelled, “the plane has hit the water once more and you are all lifeless”! I explained that if the aircraft came to a stop on the first impact, it would be very dynamic and might maximum possibly bring about complete causality, mainly for everybody now not strapped in. However, on a normal, properly carried out water landing, the plane will bypass two to a few times. Such as throwing a flat rock to skip.
Once this became mentioned, we strapped again in. After three slaps (sure my hand becomes starting to harm), I yelled, the aircraft has come to an entire forestall, EGRESS! So the cockpit group slowly made their manner down the steps to the principle shipment compartment to the crew front door. I yelled out, ahead crew front door is blocked and unable to open due to submersion! Here’s in which it gets thrilling. I cannot let you know how many crewmembers were given lost in that seat pallet! Even though they knew that the center aisle led via to the returned of the plane, a few without a doubt started out entering into between the seats to get thru it. One guy never did make it out and we ended up supporting him. Once they made it to the paratroop door area, I referred to as out that the proper paratroop door became jammed and essentially directed them through the process of illumination to the “already unlatched” paratroop door.
