Key Lime Air flight 308 December 5, 2016 ought to have been a rigorous routine. In any case, it was a part of the pilot's main position for a part of the 135 operators 5 days every week from Monday to Friday since 2008. The pilot was established at Northwest Florida Beaches Worldwide Airport (KECP) in Panama City, Florida. Key Lime Air's sole instructor was chargeable for dealing with United Parcel Service (UPS) cargo overnight stays in Southwest Georgia Regional Airport (KABY) in Albania, Georgia. Nevertheless, that evening there was something that led to the take-off of the Fairchild SA-227AC and its downfall close to Camilla, Georgia. The task of NTSB was to seek out out what occurred

In an accident report revealed on November 5, 2018, the Security Council famous that the probable reason for the accident was the decision of the pilot to start out and continue flying underneath recognized antagonistic weather circumstances, leading to regional distortion, lack of plane control and subsequent flight reduce-off. However did the pilot determine not to begin and proceed flying beneath recognized opposed climate circumstances? Or did he consider early that he would have the ability to keep in the unfavorable climate and later believed that he made the correct determination to keep away from the worst by shifting his deputy to Tallahassee, Florida?
The aircraft involved within the accident was a two-engine turbocharger Fairchild SA-227AC Metro III. It was manufactured in 1990 and was utilized by Honeywell turbocharged engines. Metrolins like this will carry up to 19 passengers, but this plane was configured to hold solely freight. There was simply over 23 233 hours on the plane's hull on the time of the accident. It was inspected as a part of a unbroken airworthiness program of just over 60 flight hours earlier than the accident. He had a current FAA first-class medical certificates. His complete flight time was eight,431 hours, of which 4,670 have been on SA-227AC. The cargo flight was supposed to go away KECP day-after-day of the week at 9.30 am east. The direct flight between KECP and KABY is 109 miles, so he only looked at 25 or 30 minutes. He often spends the night time at Albany Airport and flies again to KECP in the morning.
Event Flight Accident flight showed 51 bulk and 6 luggage of 803 kg. The announcement recognized that the gross weight of the aircraft shouldn’t be more than 14 500 kg and that the 4-internet anti-theft system prevents the movement of cargo. The take-off weight was 11,400 kilos, together with 1,400 kilos of gasoline. No cargo was recognized as "dangerous aircraft packages".
In an interview with NTSB, Key Lime Air's technical program supervisor announced that Key Lime operated 30 plane through the accident and labored with 35 pilots. The corporate is a serious cargo airline and a passenger charter. It had developed an Air Danger Evaluation Software (FRAT), which needed to be accomplished before each passenger flight but not freight flights. FRAT gave a lot of factors to varied elements that affected the flight, such as the anticipated climate and gasoline on board. If the full variety of points assigned to all elements is just too high, a management authorization must be looked for flight management. NTSB talked about Key Lime Air as CEO that the administration didn’t perceive that FRAT varieties weren’t prepared for freight flights and that it was administration management. The FRAT type was prepared by the investigators for an accident flight and found that the danger elements have been sufficiently low and that the flight might have proceeded without further obligation. This supports the pilot's determination to start out the flight.
At Key Lime & # 39; s headquarters and in Colorado, England, there were two flight followers at night time. About an hour before the scheduled departure time, the pilot routinely referred to as a flight attendant who was scheduled to handle cargo flights that night time. This flight follower informed the investigators that the pilot stated he was "keeping the ground" due to the extremely convective operation that included the activities of the twister
About 10 minutes after the pilot's examine, the cargo flight follower acquired a name from the client, UPS who needed to know if flight 308 had departed. UPS's representative expressed concern that if it wasn't quickly eliminated, the cargo would not arrive in Albany's timely integration into the united statessystem. The second flight follower invited the pilot and informed him on the invitation of the UPS. The director stated he would go away instantly and try to do it for Albany by following the clear weather. The pilot stated that if he didn’t get by means of the storms, which was then west of the flight path, he transferred Tallahassee International Airport (KTLH).
The flight was in the air at round 9:54 pm When the pilot had to modify the minor deviations, apparently he seemed to be a suitable aircraft on the Bendix RDS-81 shade radar. Key Lime Air's technical program supervisor advised the researchers that that they had preliminary and recurrent training for the pilots. "There are multimedia presentations (videos) along with the RDS-81 pilot guide," he stated.
At 10:15:22, the director checked 7000 ft at Jacksonville Middle, saying he went straight to Albany. The director really helpful, "… this side of Albany has a fairly heavy and extreme rain. I don't show breaks. Ah, just continue the deviation. Whenever you can, direct Albany, tell me if you're ready for a lower one. "The pilot replied:" Okay, yes, we will go forward and lower now and for those who will help us choose via it, we acquired the climate, weather the ship, however the help we will get is enormously appreciated. ”
10:15:55, the driving force really helpful,” Key Lime Three Eight Zero, as I stated, I don't show breaks. Uhm, there's a weaker point, but you need to be zero four to fifty thirty or forty miles before you do that shift. There’s now a fairly strong define between you and Albany, and (on the discretion of the director) (descends) to 3 thousand. ”
The pilot confirmed that 7,000 ft have been 3000 ft. At 10:16:42 director radioi: “I don't know when you’ve got fuel, however in the event you plan to stay east of this line and continue at zero to 5 zeros for about 70 miles, it's the weakest level there so we will flip again in the direction of Albanya. "The pilot replied," We’ve got gasoline, however we see what we will take a look at – we see the way it appears once we get right down to about 3,000 and let's see what the radar is painting. " "" All right, sir, "the supervisor replied.
10:18:41, the pilot knowledgeable the pilot, "I" I'm sorry, I lost simply you on your radar. I don't show the transponder. It might have something to do with the climate. “Pilot radioi:” We’ve to go away somewhat right here, I feel. "The registrar said:" I'm sorry, say again: "And the pilot responded:" We deviation to the appropriate somewhat bit here. We need to carry zero six zeros towards Key Lime three oh eight. ”
At 10:19:36, the trainer approved the pilot to show left and right as wanted and said:“ If we can get you to the other side of the line, we have vectors for ILS ya. ”
At 10:20:31, the director came again to the radio:“ Jax, uh Key Lime (incomprehensible) three zero eight, we just go back to Tallahassee. "The director replied," Key Lime three zero eight, you want to return to Tallahassee Airport? ”“ Confirm, sir, ”the director of my radio. The controller instantly investigated him "directly from his current location, maintaining 3,000." The pilot confirmed, but about half of the shipment was understandable. A couple of seconds later, the driving force asked, “Do you need to climb again up? I can supply any desired peak, Key Lime three oh eight. “The director asked for three,000 and the trainer authorised this peak and beneficial a heading of about 180's to make him clearer concerning the climate. The pilot confirmed a shift of 180 degrees, and it was the newest airplane dispatch
The Jacksonville Middle controller used an intercom system to discuss incoming visitors with a Tallahassee registrar and reported that the pilot was "… a little upset. I don't think he'll get past." I'll try to write one eighty title to him. ”A couple of seconds later, the supervisor identified,“ He's doing thirty or something out there. south, sir. ”There was no reply and the aircraft was misplaced on the radar. and take heed to the emergency locator transmitter signal, however nothing was. The calculations later showed that the plane was 40-50 degrees and the velocity different between 198 knots and 130 knots.
The shipwreck was about three.four kilometers southeast of Cam, Georgia. The waste was spread round 1/4 mile to 1/2 mile, with the rudder, the elevator and the left-wing pieces at the different end and the body on the other finish.
Analyzing engines and propellers found no indicators of mechanical problems. An airplane cab recorder can document 30 minutes on a magnetic tape. The engines might hear the vibrating sounds that the NTSB stated have been just like what you'd anticipate to hear when the airplane was in turbulence.
If the pilot might have carried out it for KABY, he would have discovered the climate circumstances for SA-227AC there were no huge deals. The incident on the time of the accident confirmed that the wind was 090 degrees 13 knots, the visibility was 8 kilometers within the rain, scattered clouds at 2,600 ft AGL and broken clouds at 12,000 ft. The temperature and dew level have been 16 degrees C.
Examination of knowledge recorded by the National Weather Service Weather Radar in the Tallahassee space confirmed that the aircraft had flown within the mild rainfall very near the front of the heavy intensive line. The climate radar antenna was about 50 kilometers from the accident website. The info stored about 6 minutes later confirmed a quickly creating heavy intensity climate that tells the airplane flight path. Knowledge recorded about 6 minutes later showed that the weather had grown from robust to excessive depth with actions that would lead to tornadoes. chooses not to cross clear and properly-grounded causes referring to excessive danger related to the flight. “If a pilot withdraws because of the climate, he won’t lose his wage. In addition, the corporate policy said that the commander is permitted to conduct operational management in all areas, enabling each flight to be safely executed to which he is assigned. It is unattainable to know from the NTSB report whether the accident pilot felt in strain, in actual or in self-creation, with out understanding that the client, UPS, asked when he was flying.
NTSB highlights a phenomenon referred to as "Get-It-Itis". It referred to the FAA Consultative Circular "Aeronautical Decision-Making", which stated: "Pilots, especially these with appreciable experience, are likely to all the time carry out the deliberate flight, please passengers, meet schedules and often present that they have" "The FAA stated that Get-There-Itis … clouds vision and weakens judgment by attaching to the original vacation spot or vacation spot, combined with a totally various strategy." Based mostly on the NTSB report, plainly the pilot had a reasonably good concept of what the climate can be that night time, was going to comply with a "clear" corridor and selected to rely on the plane's radar and clues to controlle r keep away from the worst. Tall If the pilot made a deliberate choice to fly from recognized unfavorable climate circumstances, it was not when he decided to go away, however when he refused to simply accept the controller's proposal about 70 kilometers across the storms.
