Iran Air Fokker 100 Fire at THR

Tue Mar 19, 2019 7:03 pm

https://www.rt.com/news/454241-airplane ... re-tehran/

Not a whole lot of information as of the time of this posting. Photo looks like their Fokker 100. It’s not clear to me where the fire originated.

(Edit: article updated with a clearer photo of the type.)

It is a Fokker 100. Glad everyone evacuated safely.

Iran Air Fokker 100 belly lands in Tehran

Tue Mar 19, 2019 10:23 pm

An airliner caught fire on landing at Tehran's Mehrabad airport, but all 100 passengers were evacuated without injury, officials say.

The fire broke out in the evening on March 19 after the aircraft's landing gear did not open properly, the head of the country’s emergency department, Pirhossein Kolivand, told state television.

The semiofficial news agency Fars reported that the pilot was not able to open the back wheels of the plane and circled the airport attempting to open all the wheels before landing the plane on its body.

Seems to be a regular occurrence with Iran Air and their F-100s

ASN shows 6 other Iranian F-100 gear failures. Seems rather odd. :scratchchin:

Not just an Iranian issue, the F100 has experienced gear issues throughout its time in service all around the world

Iran has relatively high amount of F-100 fleet other than PNG and Australia. Won't be surprised to see higher incident with it. Parts are hard to come by due to sanctions, so they cannabilse the older ones/those crashed to keep younger ones flying. They need F100 to perform longer domestic flight.

From that video, I fail to see that it "caught fire" as is said in the OP (probably quoted from an article). It might have happened after the end of the recording, but what you see is sparks produced by the contact of the fuselage with the concrete of the runway. No fire visible at all.

Iran CAO put out an accident notice out the next day, 20 March 2019, in Persian (I am fully fluent in Persian). I am sure the final report will be in English since foreign investigation agencies are to join.

Damage: substantial, candidate write-off

EP-IDG
49489 TH
51036 TC
as of 01FEB2019 (end of A51/C06 check)

Time: 2135 IRST

IR 215

Crew: 9
Passengers: 24


The aircraft underwent a heavy check by Iran Air (A51/C06) and returned to the active fleet on 01 February 2019. At the time it had 49489 total flight and 51036 total cycles.

The aircraft had had engine hydraulic issues on two separate flights on 16 March 2019. The engine-related systems were then tested, verified as operational, and aircraft released for flight.

On the day of incident, on a Mehrabad-Gheshm Island flight, the aircraft again encountered issues with the hydraulic system. The crew worked the checklists and returned to Mehrabad for an overweight landing. The aircraft was checked, verified as operational and released back to service. It departed again for Gheshm Island.

On the return flight and while on approach to Tehran-Mehrabad, hydraulic system number 1 failed. The alternate gear lowering mechanism for MLG, did not work. The pilots burnt fuel and then performed a gear-up landing. There was no post landing fire, only sparks from the friction with runway 29 L were noted. AARF foamed the aircraft. The plane was evacuated on the runway. There were no injuries to the occupants.


The aircraft was recovered by the Iranian Air Force to the military (south) ramp. Subsequently, it was put on jacks, gear extended, retaining pins placed and then towed to Iran Air’s hanger.


CVR and FDR were recovered, preserved and retained by the Iran CAO. Notice was given to ICAO, the British AAIB (representing the country of manufacture of the landing gear) and the Dutch DSB (representing the country of design and manufacture of the aircraft).

Initial examination showed heavy damage to the aft portion of the underbelly, landing gear doors and flaps. Further examination by the Iran Air engineers revealed faults in the mechanical connections of the MLG alternate lowering mechanism.

The CAO issued an all operator advisory regarding Fokker 100. They have been instructed to pay additional attention when testing the manual landing gear extension mechanism under dropped pressure conditions.

This incident leaves IR with only two operating F-100.

I witnessed the US F100 land in CLT nose gear wouldn’t extend. A/C 890US had pretty good damage but we fixed it and it returned to service.

Not just IR...it's pretty well known issue of the F-100 regardless of the operator.

Many thanks for translating A300!

The F100 has quite a good safety record but indeed, the landing gear is not its strongest point...

Pleasure. I am happy to translate any Persian-language civil aviation document, so long as it is in public domain and written either in Afghan or Iranian Persian. Tajik Persian uses Cyrillic alphabet that I cannot easily read.

Yep. Another aircraft, EP-ATG with Iran Aseman, had issues with deploying its right MLG on 22 March, while on approach to Ilam. It returned to Mehrabad. The gear did fully deploy on that approach. The CAO initial notice states that a post-landing inspection showed contamination of an "O-ring" in the "restrictor check valve" near the landing gear "actuator", which caused a tear in the "screen filter". Due to penetration of the contamination through the said filter, the passage for the hydraulic fluid was blocked and thus the hydraulic pressure could not transfer from the "actuator" to the landing gear.

The CAO urgent instructions to the Iranian operators of F100 include:

    At the next A-check, inspect the landing gears with additional attention directed to testing the manual extension in the condition of dropped pressure [i.e. low hydraulic pressure].

    Within 24 hours, inspect the filters as related to AD 2015-0077 and SB F100-32- 166. After further consultations with CAO, develop a procedure for recurring periodic inspection of said filters.

    Make the implementation of AD 2018-0076 a priority and inspect the "T Union" at the very next A-check. In case of any defects noted, replace with an upgraded part

It’s a Fokker 100, the F-100 was a Century series fighter built by North American Aviation in Columbus, OH. and El Segundo, CA. :D

British AAIB would be part of the investigation as the manufacturer of the engine is Rolls-Royce, not because the landing gear is British. In fact from what I can find Fokker itself is the maker of the landing gear.

@Aesema:

I thought so too: AAIB will be involved because of the RR engines. The Iran CAO notice though specifically states “the country of manufacture of landing gear.” They might have made that statement in error. There were two landing gear manufacturers: Messier Dowty and Goodrich Aerospace, as I recall.

It's a shame sanctions are preventing them of getting SSJs from Russia, I am sure these guys would have no problem in keeping them flying.

It's a shame US sanctions continue to jeopardize the lives of the Iranian flying public.
