Talk:Lockheed L-188 Electra

Untitled
I find it hard to believe that the engines tore the wings off. The only information I could find just now was this on the Lockheed P-3 Orion, which mentions the Electra. I'd look longer, but I'm supposed to be working. -rs2 18:26, 10 May 2004 (UTC)


 * Actually, this is very well-documented. See  for a good summary.  When the engines were very slightly damaged (e.g. by a hard landing), they could loosen from their mounts and begin violently oscillating, which tore the wing off. Sekicho 08:52, May 13, 2004 (UTC)

Oscillations at fuselage or wing resonant frequencies are Very Bad News. I witnessed a test of a modified Vought F-8 Crusader that was intended to induce such a resonance (for purposes of damping it out). Things went flying off the wings (weights simulating loads). At 26 Hz, all of the power of the hydraulic system went into sustaining the oscillation. Probably 150 horsepower, and very dramatic.

Electras and P-3's
Just made a small edit to the page, regarding Electras and the P-3 patrol aircraft. Though an early-build example of the Electra was used for testing the P-3 concept, P-3's were different airplanes and were new-built, not conversions from the airliner. The best way to see this is the relative positions of the wing on the fuselage - the P-3 wing is noticably further forward on the fuselage. Hatcat 03:14, 29 January 2006 (UTC)

Electras in Australia
I just added some text on the use of Electra by TAA and Ansett - replaced by 727 (branded T jets) generally in early 1960's but retained on the "Bird of Paradise" run up to Port Moresby. Used to be my "school bus" each term, to and from Sydney.

Just a note here from Canada... These planes have been modified a little bit and are used as air tankers to fight forest fires. They have the capacity to hold 2400 Gallons of water or retardent. They are operated by a company called Air Spray, based in Alberta, Canada. They are nicknamed "Electra" and are one of the biggest tankers used in fighting forest fires.

Withdrawn?
Come on, when was it withdrawn from use? Please list in the details at the top-right, in the table. --Ragemanchoo (talk) 09:26, 26 March 2008 (UTC)
 * Probably because it has not been withdrawn from use and is still operating somewhere. MilborneOne (talk) 12:22, 26 March 2008 (UTC)

ABZer (talk) 14:53, 7 October 2008 (UTC) I see one evry time I go to Aberdeen airport in Scotland. It flies up from Coventry and is an anti pollution aircraft that has fortunately never been required.ABZer (talk) 14:53, 7 October 2008 (UTC)

Argentina's use
This airplane was used during Argentina's Military Junta government during the Dirty War to toss political prisoners, the "dissappeared", into the Rio de La Plata, in the infamous flights of death. It should be mentioned on the article.

Accidents section
I have removed information regarding the 1977 disappearance of an Electra somewhere in the Carribean. With over 50 hull losses we can't list them all here, and the article has a link to the ASN page for the Electra as a reference, so those interested can quickly look at the list themselves. All except two of the crashes listed have their own articles, and the two mentioned that don't have articles involved the deaths of more than 120 people between them. The aircraft that disappeared had only four POB, and while there is no 'magic number' of deaths, the fact that not much can be said about it other than that it disappeared with four POB, suggests to me that there is little or no merit in its inclusion in the article. YSSYguy (talk) 11:07, 29 June 2011 (UTC)
 * Agree with the removal, the two non-article accidents are notable enough, soembody will write them one day. MilborneOne (talk) 11:39, 29 June 2011 (UTC)
 * Okay. Mark Sublette (talk) 12:13, 29 June 2011 (UTC)Mark SubletteMark Sublette (talk) 12:13, 29 June 2011 (UTC)

Engine mounts and LEAP
The original engine mounts had three hard points. The whirl mode induced by engine/wing resonance was understood by engineers long before the L-188 was designed. (Some 1950s a/c were so bad that they have red no-op ranges on tachometer gauges.) Lockheed certainly would have tested for this during the prototype phase. The two a/c that were lost had had their engines remounted after overhaul. It is believed that crews had incorrectly tightened the mounts. The 3-point design was not fault tolerant, and the incorrect tensions caused the fatal oscillations. LEAP changed the mounts to a 4-point type, which was much more fault tolerant. (The B767 was the first a/c to be designed from scratch with a requirement of fault tolerance in all aspects.)220.244.91.82 (talk) 09:56, 13 November 2013 (UTC)

Specifications
I noticed that some specifications (such as Payload) that appear in the article's Edit page do not show up in the article.Xmitr2 (talk) 17:45, 30 November 2014 (UTC)


 * Because they need to match the template and payload should be "payload main" and "payload alt". MilborneOne (talk) 17:56, 30 November 2014 (UTC)

Survivors
Dear Yssy, Please tell me what issues you have. Kindest of regards, Norsemanmick (talk) 02:45, 23 March 2016 (UTC)
 * The whole section relied on non-reliable sources, such as self-published websites, blogs and photos. None of these can be considered to be accurate, especially when the list included an aircraft "seen in 2007", an aircraft on an airport firedump (and therefore a candidate to be burnt for fire training purposes, if it hasn't already been destroyed), several aircraft described as derelict or in poor condition and one aircraft listed as "not seen in 2013, possibly scrapped". I saw and photographed an engineless Beech 18 turbine conversion at Tullahoma Airport in Tennessee in 2007, is that a survivor? Are the Grumman Trackers or the fin-less Boeing 707s or the semi-scrapped-but-still-fairly-complete Convair C-131 I saw and photographed in Tucson in 2008 survivors? Is the Antonov An-2 I saw and photographed at Denpasar Airport in 2013 a survivor? Who knows? Perhaps this is why other WP articles about aircraft list aircraft on display rather than survivors.

Conair Electra
The Electra that conair owned is no longer in their possession, I believe it went to a museum. I know for sure as of 2023 airspray is the only company in Canada with active electras. I found that on their Facebook page a few months ago- might be worth looking into mods! :) 23.16.63.37 (talk) 04:56, 2 October 2023 (UTC)
