LeadSong, it looks good so far. I heard about this eariler on Thursday from the S-92 article, and I have no doubt this one is notable. Good job getting it up and running. - BillCJ ( talk) 07:56, 13 March 2009 (UTC)
The CADORS report has: CHI91, S92, enroute from St. John’s (CYYT) to the Hibernia Oil Platform at 12:15Z, declared MAYDAY due to a main gear box oil pressure problem and requested to return to St. John’s. Air Traffic Control cleared the flight as requested. At 12:25Z aircraft ditched at position 472605N515658W. the times appear to disagree with the article which says ditched 9:40 and 9:48. Unless the local time is offset by an odd number of minutes? but we also have a time difference between the events. MilborneOne ( talk) 22:01, 13 March 2009 (UTC)
I'm not sure the "See Also" link to the Copterline 103 crash is appropriate; that was a different model of Sikorsky and the possible cause appears to be unrelated to the known or suspected cause at this point. Should this section be removed? Vulcan's Forge ( talk) 00:01, 15 March 2009 (UTC)
Maybe a section on current "controlled landing", i.e. ditching techniques would help.
Include accounts of successful landings, marine and terrestial and video links.
suggestions: Wiki: "Sikorsky S-6IN G-BEID" [1]

Good point. Perhaps the the main article on controlled landings, terrestrial and marine, belongs in the "water Landing" item then linked to this one later. Either way marine ditching is much more complicated. At one time pilots might have been expected to break the rotor blades before setting on the water. The "Water Landing" does not articulate the complex differences between fixed wing and rotating wing emergency landings.
Probably too soon to enter either in this main article.

That is a good link. However two points..... (1) I vaguely remember the discussions around AA-flight 191(DC-10) in 1979 that a failure of a single fastener(s) resulted in the disaster. The investigation found that it was a little more complicated than that. [4]
(2) the term "gearbox" is ambigious and vague. Speed reducers with high speed input shafts are far more sophisticated than low speed transmissions ("gearboxes") which often don't even need pressurized lubrication. A good schematic is difficult to find.

This has been edited from 91 to 491 and back at least twice now. If anyone has a confirmed reference indicating the Flight Number as 491, please include it in the references section and tag the article title or usage with it. So far all official references (the CADOR report and the flightpath website link) refer to this as Flight CHI91. Vulcan's Forge ( talk) 01:48, 19 March 2009 (UTC)
Created a 491 redirect page leading here, added the "also known as" and highlighted the CADORS report which refers to it as Flight 91. Hope that will do. Vulcan's Forge ( talk) 21:33, 19 March 2009 (UTC)
I'm not sure whether this section is appropriate or not; but since others have added it I cleaned up the text and corrected the reference since the previous reference didn't indicate the passengers and crew. Vulcan's Forge ( talk) 02:15, 7 November 2009 (UTC)
Yesterday a UK-based one-time IP editor made four edits, evidently in good faith, that seem to have drawn on sources other than those cited. These will need to be chased down. Also, the Globe and Mail cites seem to have gone behind a paywall. If a subscriber was to provide |quote=
for the relevant parts of those sources it would be helpful. Alternatively, other sources should be sought.
