F16 engine error
|
Afterburner on steroids...
|
Tragic Error The pilot was able to safely eject and did not sustain any injuries but the aircraft was destroyed as it hit the ground. |
An investigation into the mishap revealed evidence that "the main engine control was missing a required 600-degree training ring and the anti-rotation pin," according to the Air Force. |
I love the comment in the article reference in the OP:
Large portions of the aircraft, including a wing and the fuselage, were found intact after the crash, allowing investigators to identify it as an F-16, :E [and yes, I do appreciate that it's just a stupid comment by a less-than-expert journo, but it made me laugh!] |

The F-16 is equipped with a max power switch that is in place for war/emergency use only. Engaging it will allow the FTIT to increase by 20 degrees for a short duration of time giving more thrust for a bugout or what have you. It also reduces the engine overhaul time from 600 hours to just 6 hours... The use of new and more heat resistible materials in engines translates into more power or more hours between engine overhauls. The PW -232 could achieve in excess of 32.000 lbs of thrust compared to the PW -220's 25.000 lbs without any major aircraft modifications (F-16), and it could reach 37.000 lbs with a redesigned intake. That would almost get you a 1 to 1 thrust/weight in a fully combat loaded jet. Just imagine.... |

Could this have been a "retaining ring"?
AIB Report: http://www.airforcemag.com/AircraftA...16_Andrews.pdf Records indicated the mishap engine (ME), serial number (S/N) 509307, went through a modernized digital engine control (MDEC) upgrade to comply with TCTO 2J-F110-838 on 31 March 2017, and had accumulated 0.0 flight hours prior to the mishap (Tabs D-25 and U-3 to U-4). Engine Shop received the overhauled MA MEC from the supply system on 3 April 2017, and MA MEC was installed on ME S/N 509307 and passed an operational engine run test on 4 April 2017 (Tabs D-13, D-23, and J-4). 600-degree spiral retaining ring |
I love the comment in the article reference in the OP: Quote: Large portions of the aircraft, including a wing and the fuselage, were found intact after the crash, allowing investigators to identify it as an F-16, Wow! Lucky to have such experts available! [and yes, I do appreciate that it's just a stupid comment by a less-than-expert journo, but it made me laugh!] Perhaps your guffawing should be directed at the Maryland Police, rather than the journo. |

WOW, I am just imagining.... That would make it able to hover like a Helicopter...!! . .Or like a Harrier... |
Agree that more fuel than wanted means more temperature in the turbine and rapid wear-out. However, it also means more RPM and if it meters passed that emergency response line it may drive the rpms into very bad vibratory modes and fatigue of the disks in very short order.
Such possibilities will require full strip and replacement if confirmed via recorders. In this case with the plane crashed I doubt anybody is looking to reuse anything :0 |

Didn't the early Tornado used to runaway if you lost the computers?

Oh, the good old days of fuel metered directly by pilot throttle movement in those old centrifugal flow engines. :}

Don't they do an engine check run after replacing fuel control components? I'd think that would be mandatory, especially on a single engine aircraft. |
It must be a strange experience to pull back on the throttle and experience an increase in thrust. Whoa horsey.
|
Wouldn't make much difference if the fuel control was assembled incorrectly... |
