Quoting baileyncreme (Thread starter): I've had a fondness for the 727 aircraft and have recently wondered about what type of teething issues this model experienced during its design, roll out and deliveries. |
Quoting SLCGuy (Reply 2): Since jet engines don't respond as quick to throttle commands as props, several aircraft were not able to arrest the high descent rate and crashed short of the runways. I believe these crashes were at CVG , ORD, SLC, and one in Japan. |
Quoting longhauler (Reply 1): The only major "quirk" I recall, (reading about, as I was very young at the time), were the B727 "sink rate" accidents shortly after its introduction. Not a fault of the aircraft, but as the vast majority of the pilots had never flown a jet, they were not used to the spool up time of a jet engine vice a prop engine. |
Quoting SLCGuy (Reply 2): The 727 aircraft itself had very few teething problems, but an issue arose after entry into service that in todays media/online age might have doomed it. |
Quoting SpaceshipDC10 (Reply 4): They happened in just six months: on approach to ORD; on approach to CVG; at SLC and on approach to HND. |

Not a fault of the aircraft, but as the vast majority of the pilots had never flown a jet, they were not used to the spool up time of a jet engine vice a prop engine. When configured to a high drag/low speed condition, if the thrust was brought back to idle, the consequences could be and were fatal. |
Quoting longhauler (Reply 1): What always amazed me is that the time from its first flight (February 9, 1963), to its first airline delivery (October 29, 1963) to its first entry in airline service (February 1, 1964) was less than a year! |
Quoting Viscount724 (Reply 8): That was also the case for the 737, DC-9 and even the 747. The DC-9 probably holds the record with the first delivery slightly less than 7 months after the first flight, and entry into service with DL only 9.5 months after the first flight. |
Quoting tdscanuck (Reply 3): There were 5 AD's in the first year (Fuel Tank Access Panels, Flight Spoiler Actuators, Thrust Reverers, Cove Light Systems, and the Autopilot) and more than 30 in the first five years. First year had 323 Service Bulletins. By comparison, the 787 had 3 AD's in the first year and no Service Bulletins. Tom. |
Quoting type-rated (Reply 10): The ones at SLC & ORD were both UA, I believe the CVG was an AA plane. |
Quoting longhauler (Reply 11): Yes, I don't think the ORD one was a "sink rate" accident, as it was still 30 miles from the airport, and not likely in a high drag/low speed condition. When reading the report, that one is a very curious accident! |
Quoting type-rated (Reply 10): I believe the CVG was an AA plane. |
Quoting SpaceshipDC10 (Reply 12): The flight was cleared to descend from 16,000 ft to 6,000ft, but continued downward until impact. |

Quoting N243NW (Reply 17): You might enjoy this - not so much in-service problems, but an interesting overview of the flight test program... http://www.youtube.com/watch?v=5IY-j...T_sMw |
Quoting zippyjet (Reply 20): Though not a fault of the aircraft type and well after the 727 proved itself as a workhorse, the hijack craze took hold on many 727's culminating in the DB Cooper hijacking where he bailed out through the rear aft floor mounted retractible airstairs. Shortly after DB Cooper and his antics, the rear bottom stairs were sealed to prevent a repeat performance. |
Quoting 7BOEING7 (Reply 22): Actually rather than going to the trouble of sealing the door (because they wanted to use its airstair capability on the ground) they put a metal right angle mechanism that when hit by the airflow rotated 90 degrees and prevented the airstairs from opening in flight. |
Quoting type-rated (Reply 24): Speaking of the rear stairs wasn't there a case where a TW 727 near SAT had the rear stairs come open in flight and an F/A had to go down the stairs to pull the stair up so the plane could land? I believe the F/A, male, was held on to by passengers so he wouldn't fly out the opening. I seem to remember something like this happening. Maybe someone here knows more. |

Quoting type-rated (Reply 27): Did they ever bring the wreckage up? I know Lake Michigan is very deep in some spots. |
Quoting tb727 (Reply 7): You might be thinking of the TWA Convair 880 that crashed there about 2 years later while on approach. TWA flight 128. |
Quoting Newark727 (Reply 30): How was the 727-100 usually configured? |

Quoting type-rated (Reply 32): Quoting Newark727 (Reply 30): How was the 727-100 usually configured? The 727-100's usually had 4 or 5 rows of F then a galley mid ships then maybe 12-14 rows of Y. the first time I was on one, I thought the plane looked smaller on the inside than it did on the outside. Some airlines also had a forward galley too. |
Quoting SpaceshipDC10 (Reply 33): Quoting Newark727 (Reply 30): How was the 727-100 usually configured? I guess it depends of the time. In my book, there's a seating chart with 28 first and 66 economy. That configuration was apparently typical. There are six rows of four seats, plus 2x two seats opposite the galley and a large coat-storage area behind the last pair of seats. Then, there are 11 rows with six seats each, starting right after the galley. |
Quoting longhauler (Reply 39): I have a seating sticker chart (most of the old-timers on here would know what I mean) for the Eastern B727-100 dated 1979. The configuration is 12F/95Y. |
Quoting longhauler (Reply 39): 12 F seats and 21Y seats forward of the centre galley and 74Y aft of the centre galley |
Quoting milesrich (Reply 35): United started out with S class service and I think were 90 seats |
Quoting Viscount724 (Reply 37): The 727-200 had the galley moved to the front but I can't recall any 727-100s with a forward galley. How would that have worked as the only galley service door was just forward of the wing on the right hand side? |
Quoting Tomassjc (Reply 41): I can remember thinking that little "private" section of 21 Y seats forward of the center galley and coat closet on EA's -100s was pretty cool!! |
Quoting type-rated (Reply 42): I don't know how. But I do know I was on a BN 727-100 around 1971 in F and drinks were served out of the front space and meals were served out of the middle galley which covered both sides of the aisle. So you are saying that the -100 models never had a service door across from 1L? |
Quoting iceberg210 (Reply 36): If you want some great information on the launch and especially the story of HOW it ever even got off the drawing board and into the air try "Billion Dollar Battle: The Story Behind the "Impossible" 727 Project" by Harold Mansfield, excellent excellent book if you can find it, sadly out of print but there are some copies running around here and there..... |
Quoting 7BOEING7 (Reply 22): they put a metal right angle mechanism that when hit by the airflow rotated 90 degrees and prevented the airstairs from opening in flight. |
Quoting type-rated (Reply 24): DB Cooper Lock". |
Quoting type-rated (Reply 46): Thinking back it wasn't a cart because it had a bulkhead between the seats and the area. |
