AGEING AIRLINERS Notes T HE CRITERIA used here to define age ing airliners are turbine-powered air craft with accommodation for at least 30 passengers (or for a similar freight capaci ty), and built more than 15 years ago (before 1 January, 1980). The 1995 Flight International Ageing-Airliner Census cov ers 38 turbine-powered passenger and cargo aircraft types, designs with very few examples still flying being omitted*. New this year are the Ilyushin 11-86, the first of the McDonnell Douglas (MDC) MD-80 series and the Yakovlev Yak-42. Reference is included to older jet airlin ers in storage and notes (where available) recent usage for many types. Both ele ments are derived from records collated by London, UK-based Airclaims and for the Russian types by Shannon-based Russian- aviation specialist Paul Duffy. This information, covering whole fleets, includes notes for strictly older examples of those machines with high numbers of cycles (flights completed) — the accepted industry criteria for recording structural age. That data, from Aviation Research & Support (ARS) of Rugby, UK, show the rate at which the most intensively used tur bine airliners are "ageing". Whole-fleet- use data are for all aircraft in revenue ser vice (ie, not in storage or non-airline oper ation) and indicate utilisation (hours and cycles) over recent 12-month periods. Biographical notes list those variants of basic designs in service for more than 15 years and identify fleet leaders by calendar age, hours flown and cycles. Original design life is shown for these types. In rare cases, such as those of the Lockheed L-188 Electra and Convair CV-580/600/640, no design life was ever set. Information on dimensions, weight and accommodation is conservative, giving the higher value where there are alternatives. Quoted maximum weight is that of take-off. Data are taken from official and unoffi cial sources, including Flight International records. For many types listed, Airclaims is the primary source for details of fleet lead ers, numbers in service and for individual aircraft service-entry dates. ARS has pro vided additional data, while information on former Soviet designs comes from Paul Duffy and Airclaims. Inevitably, census information does not match identically data held in other international aviation databases, if only because of differing defi nitions and standards of currency. We wel come input from alternative sources, including manufacturers, operators and airworthiness authorities. *Types omitted because of few numbers still in service: Hawker Siddeley Trident IE, 2E, 3B (ten, one operator — China United Airlines, all pre-1979), BAC VClO/Super VC10 (28, but no airline), Vickers Vanguard V.950F (two), General Dynamics/Convair 880 (one), Dassault Mercure (six), Canadair CL-44 (nine), Shorts Belfast (two), VFW.614 (four), and Bristol Britannia (one) believed to be in service with Trans Service Airlift in Zaire. It was built some 35 years ago. NOTES ON TABLES To show the age of the fleet (from service- entry or year of build), the status of fleet leaders is shown — almost always different aircraft — in cycles (flights), hours flown and age, relative to the current design life. Population is given by type, collectively for pre-1968 aircraft and by year of build for 1968-78. Data are scant for many older designs — especially turboprops, Soviet designs and cargo aircraft. Some types are not supported by the original manufacturers, and US operators are no longer required to file utilisation information. Stage 3 restrictions for noise emissions. It is not unreasonable to assume that a DC- 10-30 could see active service for 28 years from new. On this basis, the last serving aircraft would retire around the year 2009. The calcu lated breakdown of the type and numbers in service today is outlined below as follows:- Model: DC-10-30 DC-10-30F DC-10-30CF TOTAL: All DC-10-30 No in service: (as of 1995) 157 12 22 191 NB The quantities above are approximate and do not include die 59 DC-10 CFs produced for the US Air Force as KC-10 tankers. Some of the above total may be in temporary storage. The table below illustrates a forecasted retire ment profile of the DC-10 30: YEAR Qty in service: 1999 191 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 180 145 116 97 85 73 59 34 9 0 (Source: Lundkvist) •ilWri'llhfiili pre-1969 Supersonic BAC/Sud Concorde - Wkiebodies Boeing 747 MDC DC-10 Lockheed TriStar - Airbus A300 Ilyushin 11-86 ll!H:fcll».U:il 1969 1970 15 Long-range narrowbodies MDC DC-8 173 Boeing 707 103 Ilyushin 11-62* 1 Medium-range Boeing 720 2 Boeing 727 373 Tupolev Tu-154* - MDC MD-80 series-- Short-range Sud Caravelle 16 BAC One-Eleven 44 MDC DC-9 353 Boeing 737 82 FokkerF28 2 Yakovlev Yak-40* 13 Tupolev Tu-134* 1 Yakovlev Yak-42 - Cargo Ilyushin II-76M/T* - 65 18 60 4 19 106 89 4 18 1 58 1 28 4 44 2 8 42 28 8 23 2 M*WH*MiW»IIIIM 1971 1972 1973 47 15 2 7 2 6 12 5 1 6 27 15 14 31 8 20 47 14 - 3 1 2 - 36 7 1 4 16 21 7 48 8 20 39 25 7 3 76 11 21 11 10 58 25 1974 21 44 37 5 9 6 81 23 36 36 5 64 46 2 1975 4 24 33 19 11 2 10 75 33 - 36 43 9 69 46 1976 4 22 15 12 15 4 14 58 56 - 2 33 33 11 70 39 1 3 1977 1 15 6 8 8 1 17 62 65 4 2 23 11 67 46 1 7 Source: Airclaims.
