BLANK CAP 776 Global Fatal Accident Review 1997–2006 Executive Summary The main risks to large public transport aeroplanes are identified through analysis of worldwide fatal accidents, which is a task carried out annually by the CAA Accident Analysis Group (AAG). The output of the AAG forms a key part of the CAA Safety Planning process in that these main risks are assessed for their relevance to the UK aviation system and, where appropriate, safety interventions are identified to mitigate them. These safety interventions can be found in the CAA Safety Plan. This document summarises a study of AAG analysed worldwide fatal accidents to jet and turboprop aeroplanes above 5,700 kg engaged in passenger, cargo and ferry/positioning flights for the ten-year period 1997 to 2006. The style and content of the document are similar to the previous Global Fatal Accident Review (CAP 681). The main findings of the study are listed below. 1 Worldwide Fatal Accident Numbers 1.1 There was a total of 283 worldwide fatal accidents, which resulted in 8,599 fatalities to passengers and crewmembers onboard the aircraft. The proportion of aircraft occupants killed in these fatal accidents was 69%. 1.2 There was an overall decreasing trend in both the number of fatal accidents and fatalities, although there was more fluctuation in the number of fatalities. 1.3 The approach, landing and go-around phases accounted for 47% of all fatal accidents and 42% of all onboard fatalities. Take-off and climb accounted for a further 30% of the fatal accidents and 29% of the onboard fatalities. 2 Worldwide Aircraft Utilisation 2.1 In the ten-year period from 1997 to 2006, the number of flights flown increased by 17%, which equated to an average annual growth of 1.5%. The equivalent values for hours flown were 31% for overall growth and 2.8% for average annual growth. 3 Worldwide Fatal Accident Rates 3.1 The overall fatal accident rate for the ten-year period 1997 to 2006 was 0.79 fatal accidents per million flights flown or 0.49 when expressed as per million hours flown. 3.2 There was a decreasing trend in both the overall rate of fatal accidents and onboard fatalities. 3.3 On average, the fatal accident rate for turboprops was three times that for jets, based on flights flown, and nearly seven times greater when using hours flown as the rate measure. 3.4 On average, the fatal accident rate for aircraft with maximum take-off weight below 15 tonnes was twice that for aircraft with maximum take-off weight above 27 tonnes, based on flights flown, and over four times greater when using hours flown as the rate measure.

  • To Our Shareholders in an Environment Where Challenges
    To our Shareholders In an environment where challenges abound, I’m proud to report the results and accomplishments of 2003. We’ve achieved these results in conjunction with a large expansion into regional jet aircraft. In spite of the challenges we maintained the integrity of our business model, provided value to our major partners through cost reductions and increased value to our shareholders. In summarizing the year, let me highlight some of our most significant achievements and successes. ¾ Added 36 net new 50-seat regional jet aircraft to the fleet ¾ Negotiated a new long-term agreement with United Airlines that was bankruptcy court approved ¾ Subsequent to year-end, negotiated an understanding with Delta Air Lines for rates and terms going forward ¾ Maintained an aggressive approach to cost reductions and containment in order to create value for our major partners and to remain competitive ¾ Reduced cost per available seat mile 11.4% $0.134 per available seat mile ¾ Negotiated a new purchase agreement with Bombardier Aerospace for additional regional jet aircraft and subsequent to year-end, increased the number of aircraft on firm order ¾ Added Continental Airlines as an additional code-sharing partner ¾ Financed all aircraft deliveries with long-term permanent lease or long-term debt and had no aircraft under interim financing arrangements at year-end I’m also happy to report that we were recently recognized for our outstanding quality wherein the U.S. Department of Transportation Air Travel Consumer Report named SkyWest Airlines as the number 1 carrier for on-time performance for calendar 2003. We added 36 net new 50-seat regional jet aircraft during the year.

  • Aviation Activity Forecasts
    2 Aviation Activity Forecasts INTRODUCTION The Charles M. Schulz–Sonoma County Airport (STS) is one of six public use airports in Sonoma County. It is the only commercial service airport1 between the San Francisco Bay Area to the south, Sacramento to the east and Arcata-Eureka to the north. The Airport’s primary service area has a population of over 1 million people2 and includes Sonoma, Lake, and Mendocino counties, and parts of Marin and Napa counties. Airport Role The Sonoma County Airport, as the region’s principal Airport, serves many roles, including providing facilities for scheduled commuter and air carrier airline services. The California Aviation System Plan (CASP) designates the Airport as a Primary Commercial Service Non-Hub Airport. There are no Primary Commercial Service Hub airports in the region. The closest Primary Commercial Service Hub airports are the San Francisco, Oakland, and San Jose International Airports. The Sacramento International Airport is slightly more distant, but at times it can be more convenient for highway travel. The Sonoma County Airport also serves a growing population of general aviation (GA) activities including corporate and business flying. For this reason, the Federal Aviation Administration’s (FAA) National Plan of Integrated Airport Systems (NPIAS) currently classifies the Airport as a General Aviation facility, but in the future the Airport is expected to be reclassified as a Commercial Service Non-Primary Airport. A strong potential exists for additional scheduled airline and commuter air carrier service, particularly in the form of new, quiet technology jet aircraft with up to 135 passenger seats.3 The Airport also serves as a base of operations for local pilots, a place to conduct business, and a point of emergency access for the region.

Using data collected from the U.S. Bureau of Transportation Statistics, we analyze 110 different aircraft types from 145 airlines operating U.S. commercial domestic service between 1991 and 2010. We classify the aircraft analyzed into four categories: turboprop, regional jet, narrow-body, and wide-body.

Gulfstream G100 The Israel Aircraft Industries (IAI) Westwind is a business jet that became a cornerstone of the Israeli aircraft manufacturing industry and remained in production for twenty years. Usually set up for seven passengers, it can carry as many as ten, or be quickly reconfigured as a fast air freight aircraft. Development The Westwind was originally designed in the United States by Aero Commander as a development of its twin-propeller namesake aircraft, first flying on 2 January 1963 as the Aero Commander 1121 Jet Commander[1]. It was of broadly conventional business jet arrangement, with two engines mounted in nacelles carried on the rear fuselage. However the wings were mounted halfway up the fuselage instead of the typical low-wing arrangement of aircraft in this class. After successful testing, the aircraft was put into series production with deliveries to customers beginning in early 1965[1]. Shortly thereafter, Aero Commander was acquired by North American Rockwell. The Jet Commander created a problem, since Rockwell already had an executive jet of its own design, the Sabreliner, and could not keep both in production because of anti-trust laws. It was therefore decided to sell off the rights to the Jet Commander, which were purchased by IAI in 1968[1]. Jet Commander production amounted to 150 aircraft in the United States and Israel before IAI undertook a series of modifications to create the 1123 Westwind.
