The design of the Lockheed L-188
Electra began in 1954, and in the following year the company received a launching order from American Airlines. The prototype, first flown on 6 December 1957, was a low-wing monoplane of conventional configuration with retractable tricycle landing gear and powered by four Allison 501D-13, 501D-13A or 501D-15 turboprop engines. Standard accommodation was for 66 to 80 passengers, but a high-density arrangement was available optionally to seat 98. Built initially as the L-188 A the Electra became available also as the longer-range L-188C with increased fuel capacity and operating at a higher gross weight. A total of 170 had been built when production ended unexpectedly early as a result of passenger loss of confidence in the type after two had disintegrated in flight, and by the time remedial modifications had been, incorporated customer airlines were interested in turbojet- rather than turboprop-powered aircraft. About half of the total built remained in service in 1992, many of them converted by Lockheed Aircraft Service for convertible passenger/cargo or all-cargo use.

The three-point engine mounts were actually Allison's fault, but Lockheed accepted responsibility. They rebuilt all machines under the LEAP program, so they had a four stud mounts angled upwards.
Many years later it was found the two supposed whirl-mode crashes had been caused by bad maintenance, rather than destructive oscillations. Oscillations of that severity become obvious to the crew well before the wings break off.

Need to contact Gus Auzins as listed above re L188 manuals

I remember taking my first flight on an Ansett Electra in 1970 with a school group from Sydney to Canberra. I am sure it was configured for passengers to be paid seating in the back (side on) lounge, or that is my memory. Tell me if I am wrong. Climbing from FL to FL was an interesting feeling.
I have a model of the Lockheed 188 with a logo with an orange star could you please tell us what airline this belong to .

I worked for zantop and unversal from 1965 to 1970. In 1968 I went amsterdam,netherlands to school at KLM on L-188 and also to allison engine school in indianaplois.

Rode 188's several times in the '60's and loved it. The very rapid accelleration that occurred when the pilot wound up the engines and unfeathered the props at the start of take-off was a real kick.

Does anyone know how far the wingtips flexed in normal flight, as compared to a B-52

I was a L.A.M.E. endorsed on the Electra and as such have in my possession set of Electra Maintenance manuuals volumes 1&2.Please contact if anyone interested.

I love this aircraft. I want to build a scale model in balsa wood. Do you know where can I to find detailed drawings or a kit ?
Thanks in advance

I made Captain on the L-188 in early 1967. It is still the most pilot friendly airplane I ever flew. I loved it !

I flew in the Electra 188 as part of $5 flight around NYC ( Out of laguardia airport)prommotion by either Eastern(?) or American(?) in 1958/59. My First commercial airline flight. I need exact info on which airline, date of promotion, copy of adverizement in paper, any info, etc. Also, anyone who flew the Electra in 50's or even flew one of these promo flights, a response woudld be appreciated.

MY HUSBAND FLEW THE P3 ORION FOR THE U.S.NAVY. HE ACCUMULATED OVER 16,000 HOURS FOR 4 DIFFERENT SQUADRONS DURING HIS 28 YEAR CAREER. FROM ADAK, SIGONELLA, JACKSONVILLE, BRUNSWICK ME. CRETE, KEFLAVIK, HAWAII, PHILLIPINES, BROWNSVILLE TX, HIS WORST MOMENTS WERE OVER THE PACIFIC IN A FLAT SPIN IN 1975, EVERYONE ABOARD SPENT A COUPLE OF HOURS AT THE O'CLUB ON ARRIVAL BACK IN THE PHILLIPINES. HE LOVED ALMOST EVERY MINUTE OF HIS L-188 EXPERIENCE.
MY 7 YEARS WITH WESTERN AIRLINES IN THE 60'S, MADE ME A BELIEVER TOO. HOWEVER I WAS FOND OF THE DC-6 JUST FOR THE HISTORY OF IT. JUDY

Flew the Electra from Jan 83 for about four years with Fleming International. With a short stint with Interstate Airlines Electra's which were the last ones built for civilian service. They where Transamerica Electra’s. They were equipped with Hamilton Standard props instead of Air Products. I then went back to Fleming which later merged with Interstate Airlines to form Cam Air. Mostly flew Air Force contracts for Logair. “Logistic Airlift Command” I was a training Captain and Check Pilot on the Electra. Had a great time in spite of the grueling hours and bad weather. Back then it was just transportation from one party to another. Flew Captain on the 727 in early 87 and left for Piedmont that fall. What a great airplane. Had many engines shut downs due to starter garlock seal leaks and propeller pitch locks etc? We had PFE’s and the Navy P-3 engineers were great. My favorite turbo prop airplane. The 727 is my favorite Jet.

Braniff Airlines had a fleet of L188 aircraft, one of which came apart in mid air in Buffalo,Texas because of harmonic vibrations. Lockheed corrected the problem by modifying the angle of attachment between the engine nacelles and the wing. The wing structure consisted of high strength aluminum planks with chemically milled risers which frequently cracked requiring repair doublers. Working as a A & P mechanic for Braniff at the time, I know first hand what it was like to crawl into the wing dry bays to install those repair doublers. Notwithstanding the wing structure issues, the aircraft systems and engine and prop combination were new to the industry and very interesting to learn about and maintain.

I have an interesting paperback about this A/C. " The Electra Story". Covers the history and accidents about this great machine.Author Robert J. Sterling. I started my F/E career with it in 1960 flying the A & C models, great memories.

Flew as a load-master in the Electra. Flying with Great Northern Airlines from 1976-1978. The a/c flew well on the North Slope of Alaska during oil exploration days.

I flew the L188 for more than 2 years for Northwwest. Donald Nyrop former president of NWA saved this airplane from the dust heap of history. NWA lost one in Tell City, Indiana and Braniff lost one in Texas I believe. Nyrop had the opportunity to ground the fleet, but instead had the autopilots taken out and put a peg speed of 250k and kept them flying until the whirlmode fix was found and fixed. I loved the airplane and consider it one of my favorites from the pilot point of view. From the pilot point of view the L188, 757 and 747-400 are the best for me. I went from the L188 to the B727 and B707 and that was a massive step back in both pilot comfort and technology.

"With the exception of the two aircraft that came apart due to gyroscopic whirlmode, all other accidents in this plane were caused by pilot error."
No, N137US crashed at ORD in 1961 when an improperly secured control cable came loose at takeoff. At about 200' altitude, there was no room to recover. My dad was the pilot.

I flew on the Eastern Airlines Electra between Louisville KY (SDF) to Chicago IL (ORD), during the Vietnam Era, many times. It seemed to be a roomy aircraft and a comfortable ride.
Do you have any comments about this aircraft ?
