I have had a pretty busy week and some of you may know that I am working on preparing a CPL(H) integrated course which has taken up a lot of my time.

However I have also been putting together some links for you with some really useful pdf’s, books and articles related to aviation safety. These are all very important and if you get this far in my blog then you really should spend a little more time checking these out.

 

Spatial disorientation as a factor in aviation accidents and incidents

Spatial disorientation is among the most common factors contributing to aviation accidents and incidents, but its true prevalence is difficult to establish. This is because many accidents where SD is cited as a likely factor are fatal, and therefore its role cannot be known with any certainty, but also because in the many instances of SD where an accident doesn’t result, it goes unreported.

 

Fixed and rotary-wing aircraft accidents involving private operations

This study provides an overview of accidents involving private aircraft operations between 2001and 2005. With approximately 400,000 flying hours conducted annually, private flying accounts for around a quarter of general aviation activity. Within private operations, rotary-wing activity now contributes about 10 per cent of all hours flown.

 

NTSB Safety Recommendation : R22 Main Rotor Divergence Incidents

NTSB Safety Recommendation for R22 Main Rotor Divergence. Looking at 3 accidents in detail which involved some fairly experienced helicopter pilots and which were fatal. Includes an appendix of 21 R22 loss of main rotor control accidents.

 

Loss of control accidents in lightweight helicopters

Flight Safety Foundation article on loss of main rotor control accidents to lightweight helicopters, focussing on the R22 and R44 and the introduction of SFAR-73 and the virtual elimination of Low-G mast bumping incidents as a result.
Fatigue in Aviation FAA document on the affects of fatigue US Mil Report on spatial disorientation accidents Spatial disorientation in US Army Helicopter Accidents. An update of the 1987-92 report to include 1993-95. NTSB Safety Recommendation : R22 Loss of Main Rotor Control NTSB Safety Recommendation to the FAA about the Robinson R22 and loss of Main Rotor Control accidents.     FAA Advisory Circular on LTE The FAAs original document with description of and advice on LTE.       Helicopter Performance Another widely overlooked subject in Ireland, this short leaflet gives advice and examples about when, where and how to perform helicopter power checks and performance assesments.     Flight Safety Foundation LTE Article Flight Safety Foundation document which looks at an LTE accident in detail.       Preventing Dynamic Rollover Flight Safety Foundation Article on preventing dynamic rollover. The circumstances necessary to achieve dynamic rollover. A simple physical description and suggests methods for prevention. Also included is a short article on main rotor icing, with no visible sign on the airframe.   Unanticipated Right Yaw at low speeds Filght Safety Foundation Article on LTE from the late 1980s. Also included is a short article on a maintenance error which caused the loss of a Whirlwind.     Light Utility Helicopter Safety in Australia The aim of this report was to determine if any particular light utility helicopter model has a higher risk profile than similar aircraft. For each of the light utility helicopter models the report compared accident trends (fatal and non-fatal), accident rates per registered aircraft, fatal accident rates per hours flown and accident rates per hours flown.   Helicopter Wake Vortex Notice to aerodrome licence holders issued after a light fixed wing aircraft crashed after an encounter with the wake vortex of an S61 helicopter.       CAA Paper 2003/01 Helicopter Tail Rotor Failures An incredibly detailed look at Tail Rotor Failures across a broad spectrum of helicopter types. The prevention of future tail rotor failures by various methods is examined, and suggestions for how to deal with tail rotor failures are made.   CAA Paper on Flight in Degraded Visual Conditions An excellent but technically complex study of flight in reduced visibility. Several UK accidents are looked at in detail, and virtually every accident in the CAA database that related to poor visibility until the study started gets a mention somewhere. Almost 200 pages but well worth reading if you get the time.    Helicopter Safety Sense Leaflet Almost every helicopter pilot will probably realise they don’t do something they should be doing from reading this short but very informative leaflet.

John, This is a great site with amazing insight into many facets of helicopter flying. I really love the safety articles along with the practical tips for better flying. The site is very well laid out and easy to follow. Keep up the good work and I hope to catch up with you in person soon.
Sincerely yours,
Breandán.

Nice blog post. Just an idea though – you really should think about submitting your posts to reddit – Seems to me like the readers there should be interested in your posts; also it’ll get you extra readers.
