USAF F-35A Flight Operations Halted at Luke AFB, Oxygen Supply Problems Cited

Five Pilots Report Symptoms Similar to Hypoxia.

The U.S. Air Force has reported that flight operations for F-35A Lightning II aircraft at Luke AFB near Phoenix, Arizona in the United States have been temporarily halted.

USAF Brig. Gen Brook Leonard, commanding officer of the 56th Fighter Wing that operates the F-35A, said in a press release that, “In order to synchronize operations and maintenance efforts toward safe flying operations we have cancelled local F-35A flying.”

The announcement that appeared on the official Luke AFB website via the U.S. Air Force Office of Public Affairs stopped short of calling the temporary halt to flight operations a “grounding”.

It is possible Air Force officials are using caution in references to any halt in flight operations to avoid potential associations with a series of incidents on the F-22 Raptor from early 2012 with crew life support equipment, specifically the oxygen system. The incidents from 2012 led to a sensational expose’ on the U.S. investigative reporting show “60 Minutes” in which two Virginia Air National Guard pilots said the F-22 was unsafe to fly due to problems with its crew life support system. Additionally, in March of this year U.S. Navy officials told U.S. Congress there was an increase in “physiological episodes” in the long successful Boeing FA-18 Hornet.

The official Air Force news release reads, in part, “According to base officials, since May 2, 2017, five F-35A pilots assigned to Luke AFB have reported physiological incidents while flying. In each case, the aircraft’s backup oxygen system operated as designed and the pilot followed correct procedures, landing the aircraft safely.”

The Air Force statement went on to say, “Wing officials will educate U.S. and international pilots today on the situation and increase their awareness of hypoxia symptoms. Pilots will also be briefed on all the incidents that have occurred and the successful actions taken by pilots to safely recover their aircraft.”

Capt. Mark Graff, an official U.S. Air Force spokesman, said the temporary halt of F-35A flight operations was done, “not out of fear or out of danger, but out of an abundance of caution,” Capt. Graff also told news media that the Air Force plans to resume flight operations on Saturday.

The temporary halt of flight operations includes 55 of the U.S. Air Force F-35A’s at Luke AFB. The story is contrasted by a lengthy phase of successes for the F-35 program that include successful deliveries to international F-35 users like Japan and Israel, operational deployments of the U.S. Marine F-35B V/STOL version to Japan and major deployment of Air Force F-35As to Europe.

 

Two U.S. F-35s Have Deployed To Bulgaria Today

The U.S. Air Force F-35A Lightning II aircraft continue their tour of eastern Europe.

On Apr. 28, two U.S. Air Force F-35A Lightning II aircraft, 14-5094 and 14-5091, belonging to the 34th Fighter Squadron, from Hill Air Force Base and temporarily deployed to RAF Lakenheath, UK, arrived at Graf Ignatievo Air Base, Bulgaria.

The aircraft were supported by a single KC-135R Stratotanker, c/s “Nacho 81”, from 459th Air Refueling Wing, Joint Base Andrews, Maryland, that launched from RAF Mildenhall.

Interestingly, the 5th Gen. aircraft used the very same radio callsigns used by the F-35s involved in the JSF’s first ever visit to Estonia on Tuesday: “Conan 01” flight.

According to the U.S. DoD, today’s training deployment has been planned for some time and was conducted in close coordination with Bulgarian allies. “It allows the F-35A the opportunity to engage in familiarization training within the European theater while reassuring allies and partners of U.S. dedication to the enduring peace and stability of the region.”

“The aircraft and Airmen began arriving in Europe on April 15, and are scheduled to remain in Bulgaria for a brief period of time before returning to RAF Lakenheath to continue their training deployment.”

Already deployed to Graf Ignatievo Air Base, to take part in exercise Thracian Eagle 2017 were also 12 F-15C Eagle jets belonging to the 122nd Fighter Squadron of the 159th Fighter Wing, Louisiana Air National Guard that are in the involved in the drills along with the local-based Bulgarian Air Force MiG-29s as well as Su-25s from the Forward Deployment Air Base at Bezmer, L-39s from the Air Training Group at Dolna Mitropoliya Air Base, AS-532 AL, Mi-24 and Mi-17 helicopters from Krumovo Air Base, and air defence units.

Whilst “Nacho 81” could be tracked during its flight (to and back from) Bulgaria, this time the deployment to eastern Europe was not “accompanied” by any evident activity by U.S. or NATO intelligence gathering aircraft. In contrast, as already reported, on Apr. 25, flight tracking websites exposed the presence of a U.S. Air Force RC-135U Combat Sent, an RC-135W Rivet Joint and a RAF Airseeker over or around Estonia.

15 F-35As (13 USAF and 2 RNoAF) Grounded By “Several faulty cooling lines discovered in their wings”

15 F-35A have been grounded at Luke Air Force Base after faulty cooling lines were discovered.

Several faulty cooling lines have been identified in the wings of some F-35A aircraft at Luke Air Force Base, leading to the decision to temporarily suspend flight operations.

Noteworthy, the issue does not involve all the CTOL (Conventional Take Off and Landing) examples but 13 U.S. Air Force and 2 Royal Norwegian Air Force F-35As. Interestingly, among the 4 aircraft already delivered to the Norwegians, only the third and fourth F-35 received at the Partner Training Center at Luke Air Force Base are affected by faulty components.

Some details about the grounding were just released by RNoAF.

The F-35, just like several other aircraft, uses its fuel tanks as part of its on-board cooling system: this imply that several cooling lines have been installed inside the tanks to allow cooling liquid for the aircraft’s avionics and other systems to pass through.

During a routine depot maintenance of one of the American planes it was discovered that the insulating materials covering the cooling lines have decomposed, leaving residue in the fuel.

The subsequent inspections have confirmed the same kind of issue with other aircraft fitted with cooling lines from the same provider.

According to the Norwegian MoD the issue has been traced back to cooling lines manufactured by one particular provider that have only been installed in the wing fuel tanks of 15 aircraft – 13 US and 2 Norwegian. However, an additional 42 aircraft currently on the production line have received parts from the same provider (including the three Norwegian aircraft scheduled for delivery early next year).

“We have been very pleased with our aircraft so far, both in terms of performance and technical capabilities” says the release that goes ahead with more information about the problem: “This is not a design flaw, but is instead caused by a supplier using improper materials and improper sealing techniques for these specific parts.”

Major General Morten Klever, the director of the Norwegian F-35 Program Office says he expect Lockheed Martin to identify the appropriate measures to correct this issue, and implement these as quickly as possible.

“This appears to have been an isolated incident. We expect this to be resolved by the time we receive the next aircraft currently in production. The F-35 will be key to our ability to defend Norway over the coming decades, and consequently we have imposed very strict requirements on the aircraft,” says Major General Klever in the official Norwegian statement on the grounding.

Since not all the aircraft are affected by the issue, pilots at Luke Air Force Base will be able to continue their training using other aircraft at the base, including the other two Norwegian jets as well as the Italian and Australian examples.

First Italian pilot qualified as F-35A Instructor Pilot at Luke Air Force Base

Italian Air Force fighter jock becomes fully-qualified F-35A IP at Luke AFB.

An ItAF combat pilot has recently become the first Italian F-35A IP (Instructor Pilot) with the 56th Fighter Wing at Luke AFB, Arizona.

The Italian IP has got the qualification to train Italian and partner nations pilots on the Joint Strike Fighter through a 6-month syllabus made of two distinct classes respectively called “Transition” and “Intructor Pilot Upgrade” (IPUG).

During Transition the pilots train in various forms of flight: air-to-air combat, air-to-ground missions including SEAD/DEAD tasks (Suppression / Destruction of Enemy Air Defenses). At the end of this stage, the student IPs have gained skills to fly these missions in all-weather conditions.

During the subsequent IPUG class, the students are taught how to teach follow-on pilots to fly and fight in the F-35A. The IPUG course ends with a check ride required to achieve the IP qualification.

The syllabus has become more focused on full combat training last Spring, as the U.S. Air Force prepared to declare the F-35A Lightning II ready for war by the U.S. Air Force with the 34th Fighter Squadron based at Hill AFB in Utah (that eventually achieved the Initial Operational Capability on Aug. 2).

[For a detailed analysis of the IOC milestone, please read our report published here.]

The newly qualified Italian IP will serve in the multinational pilot training center at Luke AFB in Arizona, the world’s premier conventional F-35 training base where, under a pooling arrangement, USA, Australia, Norway and Italy, share IPs and aircraft to train new pilots and instructors within the same standardized framework.

Two Italian F-35As are already part of the “shared pool” at the airbase near Phoenix: the first one, dubbed AL-1 and serialled MM7332, the ItAF’s first F-35, the first JSF built outside the U.S., arrived in the U.S. at the end of the type’s first ever transatlantic flight on Feb. 5, 2016.F-35 ItAF IP 2Image credit: ItAF
