Warship Tour of duty, 7pm BBC2 covers the F35 accident
Title says it all. It’s the F-35 jet launch disaster episode.
so I take it is the one over the side in the ogging. Sky channel 102 |

Given that my £5,000 car won’t start unless the clutch is depressed, it amazes me that a cutting-edge technology £xxx million jet can get as far as trying to take off with an engine blank installed. Staggering.

Read the BoI.
engine blanks were simply the last in a huge and quite concerning error chain. |
I take it the shotgun used to scare the birds were firing some of these and not just standard cartridges.
https://www.wildlifecontrolsupplies....NWS15MMBB.html I am surprised in this day and age they do not have something built into the ramp similar to something like this https://portek.co.uk/portfolio/scatt...aring-gas-gun/ rather have three men and a shotgun having to walk down the front and let rip with a shotgun. |
Navy Lookout's long and highly critical take on the event and the investigation findings: The F-35 accident report – a reality check for UK Carrier Strike | Navy Lookout

Every jet that I’ve worked on with twin intakes had the two blanks connected and a warning flag. Basics that seem to have been forgotten in this new air force.

I don't think there is a positive sentence in that entire report! |

"...A Royal Navy Board of Inquiry led by an experienced Fleet Air Arm fixed wing carrier pilot and supported by a Naval Air Engineer and a Surgeon Commander would undoubtedly have addressed all these important issues [five listed earlier] and produced a more concise and relevant Report...." |

"...A Royal Navy Board of Inquiry led by an experienced Fleet Air Arm fixed wing carrier pilot and supported by a Naval Air Engineer and a Surgeon Commander would undoubtedly have addressed all these important issues [five listed earlier] and produced a more concise and relevant Report...." And what does Sharkey think demanded an experienced Fleet Air Arm fixed wing carrier pilot? The accident was nothing to do with pilot handling, all the error chains being organisational or human factor-related. As for a Surgeon Commander, only if he or she had some serious HF knowledge that would be unusual for the medical profession; it is why the AAIB has an HF Inspector and not a doctor on the team. |

I guess it is career suicide for any light blue officer to suggest that naval aviation is anything more than aviation from a floating airfield, but this accident drives that point home. |
I don't think it really matters who or what wrote the report. In short order an interim report should have been issued to DG DSA:
'Once again an accident has been caused by the total breakdown of all eight Defence Lines of Development. Our recommendation is to do what you're meant to be doing'. But that would need an SI president who was retiring that same day...! |
This was first aired on the BBC programme back in the Spring. Lots of embarrassed faces around. Can't recall if the carrier's commander left his post before or immediately after - cause or effect?
The pilot had one helluva shaving rash, a consequence of the det cord in the canopy. |

It still tickles me that in spite of this, the BoI report had an unredacted photo down the intake, but redacted captions on pictures of the ski ramp and deck lift!(Although someone suggested that the photo may be of a mock-up rather than a real F-35) In this instance, the Government Special Access Programme Security Officer (GSSO) responsible for maintaining the secrecy of some aspects of the F-35, ordered them to be fitted for the visit to Oman and the transit of the Suez Canal, although gave no instruction when they should be removed. The intake ducting is designed to shield the fan at the front of the F-35’s engine from radar in order to help maintain the aircraft’s stealth. This feature is covered when it might be viewed close up by those without security clearance. |
Even 30 + years ago I had to certify in the (civilian HS748) Tech Log that all pitot/static covers, gear pins and engine blanks had been removed before flight. What's the RAF/RN/AAC paperwork process to prevent oversights these days?

Hermes Badgers certainly used live 12-bore ammo to disperse the local sheathbills on the ramp during Corporate. The Old Man nearly had epilepsy when he found out; quotes of Ancient Marriner, albatross and associated dread outcomes. Not that he was superstitious!

I have worked for two Air Forces and in both it was standard practice when preparing a fighter for flight to lay out the aircraft blanks/locks for the pilot to see when he arrived at the dispersal.
After he had checked that all were accounted for they would then be stowed as appropriate while the pilot did his external pre-flight checks. It was the responsibility of the pilot and airman in charge of the see-off crew to ensure all were accounted for. I have never heard of an intake blank being left in during an engine start. In a twin intake aircraft the blanks should be joined by a length of tape/cord. That way you cannot forget one. It would seem that standards have dropped very badly and somebody in authority needs his a**e severly kicking. CC |
There are many variables on this subject, perhaps the least of which is aircraft type or civil/military. Consider conspicuity of the blank/flag combo, consequence of premature removal, remoteness of the aircraft from its tech-log/Form700, and authorisation of personnel to certify removal. Every cover, blank and lock is there for a reason, and its removal introduces a potential risk. For instance, the tech log requires certification for removal of all devices before acceptance by flight-crew; a particular concept of operation now requires the aircraft to be parked on a dispersal or flight-line several hundred metres from the flight office, and the aircraft is therefore parked for at least several minutes without prop-strops or gust-locks. There isn't a one-size-fits-all regime.
What is important is that for each organisation, fleet and type of operation, the responsibilites of every member of the ground/flight team are well thought out (day/night, fair-weather and foul), promulgated in procedures, and adhered to by everyone, every time. |

Perhaps it starts at the design stage? The F35 intake blanks look like they are pushed into the intake. If one is removed without the other, could certain wind conditions suck the other to the back where it cannot be seen. Would it be better to have a cover that sat over the intake lip so nothing of the cover ever actually penetrated the intake. They could then easily be connected. Just a thought. |
C130 Intake blanks
During my time on Albert, from 1967 to 1994 with some gaps, pitot head covers were removed and draped over the external power cable or if no cable, draped over the crewdoor between the support arm and the door so the door could not be closed. Both locations were obvious and needed a further action before departure, removal of grpund power or trying to close the crew door.
Where, as in geographically, they placed the pitot blanks on the nose lock happened I don't know as I have never heard of such a stupid procedure almost designed to cause problems! Attempted takeoffs with the nose lock in did take place but not in any great number, normally followed by a quick circuit, appearance of growbag from Albert, grovel in the nose wheel bay, swift take off and disappear followed ultimately by a few slabs for the boys from the eng. |

Most intakes in my experience had blanks that were oversized and could not be pushed inside beyond the opening, what is it about the F35 one that requires placement so far down the intake as to render it not visible? |
The MOD report concludes the sole cause of the incident was a LH (port) intake blank located inside the aircraft intake becoming pinned against the engine inlet guide vanes thus restricting airflow during the critical take off phase.
The F35 intake blanks in use at the time of this incident were the latest version, a plug type fitting whereby they were physically manipulated into position and held in place by friction; the only security was by the use of a single quick release pip pin secured to a lanyard which could be physically attached into the aircraft skin. The LH (port) intake blank recovered from the sea immediately after the ditching of BK18 was recovered intact with the pip pin/lanyard inside the stowage pocket This occurrence was not the first time of happening (for F35 Operators) and had been formally recorded on many previous occurrences; the report stated that other similar incidents had also taken place but had not been officially reported. The F35 community had been advised of previous (intake blank) incidents and thus were aware of the potential for ongoing incidents to become an accident Such was the level of concern about other potential shortcomings that the report makes no fewer than 46 recommendations for things that should be changed going forward. The panel further concluded;-
This has turned out to be an expensive and very embarrassing incident for all concerned including the US Military, the only good thing is that everyone walked away with a story to tell. |
I think, reading the report, there were a lot of other issues involved - lack of routine, lack of records, crew kept off the deck for "security" reasons etc etc.
yes the blank should have been noticed but the overall report suggested all was not well with the operation overall. :( |

I have a better idea to prevent re-occurrence of this incident:- That the crew preparing the aircraft for flight do the job that they are trained to do!! CC |

It's not like we did this 'just give-it-a-go, what-could-go-wrong cruise' in front of a 'skeleton' detachment of US Marines that still outnumbered the UK by over a 100, or deployed NMC capable jets in the hope they could be fixed at sea. That could have been really embarrassing... |
