About MD-82:

Announced on April 16, 1979, the MD-82 (DC-9-82) was a new MD-80 variant with similar dimensions to those of the MD-81 but equipped with more powerful engines. The MD-82 was intended for operation from 'hot and high' airports but also offered greater payload/range when in use at 'standard' airfields.[61] American Airlines was the world's largest operator of the MD-82, with at one point over 300 MD-82s in the fleet.

Originally certified with 20,000 lbf (89 kN) thrust JT8D-217s, a -217A-powered MD-82 was certified in mid-1982 and became available that year. The new version featured a higher MTOW (149,500 lb (67,800 kg)), while the JT8D-217As had a guaranteed take-off thrust at temperatures up to 29 °C (84 °F) or 5,000 ft (1,500 m) altitude. The JT8D-217C engines were also offered on the MD-82, giving improved Thrust specific fuel consumption (TSFC). Several operators took delivery of the -219-powered MD-82s, while Balair ordered its MD-82s powered by the lower-thrust -209 engine.

The MD-82 features an increased standard MTOW initially to 147,000 lb (66,700 kg), and this was later increased to 149,500 lb (67,800 kg). Standard fuel capacity is the same as that of the MD-81, 5,840 US gal (22,100 L), and typical range with 155 passengers is 2,050 nmi (3,800 km).

About Lion Air Flight 538

Lion Air Flight 538 (JT538/LNI538) was a scheduled domestic passenger flight from Soekarno–Hatta International Airport, Jakarta, to Juanda International Airport in Surabaya, with a stopover at Adi Sumarmo Airport, Surakarta, Indonesia. On 30 November 2004, the McDonnell Douglas MD-82 overran the runway of Adi Sumarmo Airport, and crashed onto a cemetery on landing; 25 people on board were killed in the crash, including the captain. Investigation conducted by the Indonesian National Transportation Safety Committee concluded that the crash was caused by hydroplaning, which was aggravated by wind shear.
