This AD is prompted by additional focused inspection procedures that have been developed by the manufacturer. The actions specified by this AD are intended to prevent the failure of critical, life-limited, rotating engine parts, which could result in an uncontained engine failure and damage to the airplane. Due consideration has been given to the comments received. The FAA disagrees. After assembly at manufacture, the HPT disk and shaft essentially can be treated as a single part. The HPT disk and shaft are not required to be separated at overhaul unless there is unrepairable damage to one of the parts or one of the parts has reached a time limit. Further, separation of the parts can cause mechanical damage to the tie rod holes that requires additional repair. The FAA does not want to force the separation of the disk and shaft at every overhaul but does want to have the HPT disk inspected at each opportunity throughout the life of the disk. Therefore, in order to provide a sufficient number of opportunity inspections over the life of the HPT disk, the original equipment manager (OEM) developed an inspection of the disk and shaft assembly. Further, the OEM has addressed problems associated with the prototype process in the final approved inspection process for the disk and shaft assembly. Accordingly, this AD requires changes to the life-limits section that incorporate that inspection of the disk and shaft assembly.http://epponline.com/mentorfinancial/page_images/1957-cessna-172-parts-manual.xml The commenter states that air carriers that use the affected engines may not have had an opportunity to comment on the inspection procedure. The FAA disagrees. The FAA believes that the nature and scope of the added inspections will not differ significantly from existing inspection procedures. In addition, the FAA has set the effective date of this AD at 180 days after publication to allow time for the manufacturer to include these specific inspection procedures in the next revision of the Engine Manual. Operators may submit additional comments on those inspection procedures and the FAA will consider either extending the effective date further or additional rulemaking, as necessary. The FAA does not believe, however, that this final rule need be delayed pending publication of the inspection procedures. The FAA agrees and the effective date of this AD has been extended to 180 days after publication to allow time for the specific procedures to be published. The extra time until the AD becomes effective should allow the manufacturer to issue a manual revision. The FAA agrees in part. As the commenter notes, the FAA had previously viewed the engine manual for this engine model to be structured so as to make reference to “all” part numbers impractical. The FAA has reviewed the engine manual again and the proposed new changes and determined that individual part numbers may be removed. Therefore, this AD references “all” part numbers, Start Printed Page 44528 as with other engine lines. The decision not to include part numbers was originally made to accommodate the industry. The removal of part numbers eliminates the requirement to modify the TLS and Continuous Airworthiness Maintenance programs every time a new part number is introduced by the manufacturer for those parts covered by the AD. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.https://www.informaquiz.it/petrgenis1604790/status/flotaganis21052022-2330 A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption ADDRESSES. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it. Operators must submit their requests through an appropriate FAA Principal Maintenance Inspector (PMI), who may add comments and then send it to the ECO.

Cockpit indications revealed rapidly declining N1 (low-pressure compressor) and N2 (high-pressure compressor) readings on the number 1 engine gauges. The exhaust gas temperature (EGT) had exceeded the highest temperature on the gauge, and the cockpit crew immediately shut down the faulty engine. The crew declared an emergency, landed uneventfully, then taxied back to the departure gate.Company maintenance personnel found evidence of extremely high temperatures in the turbine sections. Turbine nozzle guide vanes were intact but revealed heat distress on the trailing edge. The high-pressure turbine (HPT) blades had melted from about 30 degrees of the span and outboard. All three stages of the low-pressure turbine (LPT) had melted at various lengths, and solidified pools of metal had formed on the inside of the exhaust nozzle outlet. Noticeable damage to the 3 rd stage compressor disk was also discovered, however, there was no evidence of foreign object ingestion.Maintenance personnel then followed the engine manual instructions and replaced the pressure ratio bleed control valve and the start bleed control valve. Inspection of the compressor section was not carried out, nor was it required according to the engine maintenance trouble-shooting instructions.Compressor stalls can cause reverse bending of the compressor blades, causing fatigue fractures, resulting in engine failures such as seen in this particular event.Surges should be considered minor stalls and should not be underestimated in the damage that can occur. It is evident that compressor surges and stalls can induce latent fatigue fractures culminating in engine failures. Something went wrong.

Today, there are 2,400 engines still in use. The eight models that make up the JT8D family cover a thrust range from 14,000 to 17,000 pounds. The JT8D-200 series, which entered service in 1980, offers 18,500 to 21,700 pounds of thrust, and is the exclusive power for the popular MD-80 series aircraft. The JT8D-200 builds on the family's excellent reliability and low maintenance costs while meeting noise and emissions regulations. The E-Kit reduces JT8D-200 engine NOx emissions by 25 percent and exceeds all ICAO standards for new production engines.By using our website, you agree to our use of cookies. The performance is based on an engine failure at the critical point during takeoff and a 15 ft. Manual J 8th Edition Video This article needs additional citations for. It was a modification of the engine, which powered the. The is an afterburning version that was license-built in Sweden for the fighter. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. Six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream) turbine (which consists of three stages); and a second rotating assembly for the high-pressure compressor (HPC) section, which has seven stages. The high-pressure compressor is driven by the first (upstream) turbine, which has a single stage. The front-mounted bypass fan has two stages. The annular discharge duct for the bypass fan runs along the full length of the engine, so that both the fan air and exhaust gases can exit through the same nozzle. This arrangement allows some noise attenuation, in that the still-hot fast-moving turbine exhaust is shrouded in much-cooler and slower-moving air (from the bypass fan) before interacting with ambient air. Thus the JT8D noise levels were significantly reduced from previous non-turbofan engines, although the low meant that, compared to subsequently developed turbofans, high noise levels were still produced. Eight models comprise the JT8D standard engine family, covering the thrust range from 12,250 to 17,400 (62 to 77 kN) and power, and aircraft. More than 14,000 JT8D engines have been produced, totaling more than one-half billion hours of service with more than 350 operators making it the most popular of all low-bypass turbofan engines ever produced. Within the fan inlet case, there are air bosses and probes to sense the inlet pressure and temperature. Similar units exist throughout the engine to check temperatures and pressures. At the 13th (i.e. The final) compressor stage, air is bled out and used for anti-icing. The amount is controlled by the Pressure Ratio Bleed Control sense signal (PRBC). The diffuser case at the aft end of the compressor houses the 13th stage. Its increasing cross-sectional area allows the compressed air to slow down before entering one of the engine's nine burner cans. Again, there are two bosses to extract 13th stage air for anti-icing, de-icing of fuel, and airframe (cabin pressurization) use. Not all the compressed air enters the burner cans at the fuel-ignition point; some bypasses the can completely and cools the first turbine stage, and some is gradually introduced into the burner can's perimeter in such a way that the burning fuel is held near the can's centerline. There are nine combustion chambers positioned in a can-annular arrangement. Each chamber has three air inlet hole sizes: the smallest is for cooling, the medium is for burning and the large for forming an air blanket. Update programs In response to environmental concerns that began in the 1970s, the company began developing a new version of the engine, the JT8D-200 series. Designed to be quieter, cleaner, more efficient, yet more powerful than earlier models, the -200 Series power-plant was re-engineered with a significantly higher (1.74 to 1) covering the 18,500 to 21,700 pound-force (82 to 97 kN) thrust range and powering the. This increase was achieved by increasing bypass fan diameter from 39.9 inches (101 cm) to 49.2 inches (125 cm) and reducing fan pressure ratio (from 2.21 to 1.92). Overall engine pressure ratio was also increased from 15.4 to 21.0. Since entering service in 1980, more than 2,900 of the -200 series engines have been produced. JT8D-219 on the Omega Air Boeing 707RE flight test aircraft at the The JT8D-217 and -219 engine(s) were tested in 2001 and were deemed suitable replacements for the old engines on military and commercial aircraft as part of the Super 27 re-engining program. The updated engines offer reduced (Stage-3) noise compliance standards without the need for hush kits, enhanced short field performance, steeper and faster climb rates with roughly a 10 reduction in fuel burn for extended range. Northrop Grumman used the -219 to re-engine one of the United States Air Force’s fleet of 19 Joint Surveillance Target Attack Radar System aircraft, which will allow the JSTARS more time on station due to the engine's 17 greater fuel efficiency. NATO also plans to re-engine their fleet of AWACS aircraft. The -219 is publicized as being half the cost of the competing 707 re-engine powerplant, the, for reasons of geometrical and balance similarity to the engine it is replacing and the associated relative up-front wing modification costs of the two choices. Jt8d Engine Cutaway A minute later, Flight UA266 lost power to its second engine. 13 minutes post take off, the plane crashed into the Pacific OCean, just 12 miles off the coast, killing all 38 souls on board, to include 32 passengers, and 6 crew members. 4 April 1977 - both engines on the failed when the pilots flew into a severe thunderstorm after misreading their onboard radar. The flight encountered severe rain and hail. The NTSB concluded that the 'loss of thrust was caused by the ingestion of massive amounts of water and hail which in combination with thrust lever movement induced severe stalling in and major damage to the engine compressors.' 63 people on-board and 9 on the ground died as a result of the accident. 22 August 1985 - an engine failed during take-off from and a fire spread into the cabin, resulting in 55 fatalities aboard the -236 Advanced. 3 May 1991 - Unconfined failure of 9th stage compressor disc penetrated fuel lines and fuselage on the tarmac at causing fire and complete loss of aircraft. Manual J 8th Edition No fatalities reported. 21 December 1991 - The engines on an MD-81 ingested wing ice during takeoff causing engine damage that led to a total loss of thrust on both engines. The aircraft crashed in a forest clearing with no fatalities. 6 July 1996 An engine explosion happened on an, just prior to take-off at, USA, with two fatalities. 15 April 2008 A operated by and burned at following an engine fire, with 40 fatalities.
