The Embraer ERJ 135 regional jet is one of the Embraer ERJ 145 family. Family members include the ERJ 140, ERJ 145, and Legacy, with the ERJ 145 being the largest of the group. The series are powered by two Rolls-Royce AE 3007 turbofan engines. Primary competition comes from the Canadair Regional Jet.

History

Please see main article Embraer ERJ 145 family

Derivatives

The ERJ 135 is based on the ERJ 145 with 96% parts commonality and the same crew-type rating. The only significant changes are a shorter fuselage, a slightly de-tuned engine and an increased range. The ERJ 135 has 95% parts commonality with the ERJ 145, but is 11.7 feet (3.6 m) shorter.

The ERJ 135 seats 37 passengers, while the ERJ 140 seats 44, and the ERJ 145 seats 50.

Operations

The first flight of the ERJ 145 was on 11 August, 1995, with the first delivery in December 1996 to ExpressJet Airlines (then the regional division of Continental Airlines). ExpressJet is the largest operator of the ERJ 145, with 270 of the nearly 1000 ERJ 145s in service. The second largest operator is American Eagle, with 206 ERJ 145 aircraft. Chautauqua Airlines also operates 95 ERJ 145s through its alliances with American Connection, Delta Connection, US Airways Express and United Express. By some accounts, the ERJ 145 has a cost of ownership of about $2,500,000 per year.

Models

Airline models

  • ERJ 135 ER - Extended range, although this is the Baseline 135 model. Simple shrink of the ERJ 145, seating thirteen fewer passengers, for a total of 37 passengers.
  • ERJ 135 LR - Long Range (increased fuel capacity and upgraded engines).

Business models

  • Legacy - Business jet variant is special variant modeled after an ERJ135. Main Article: Embraer Legacy

Civilian operators

As of August 2006 a total of 113 ERJ 135 aircraft (all variants) remain in airline service, with 1 further firm order. Major operators include: American Eagle Airlines (39), Chautauqua Airlines (17) and ExpressJet Airlines (30). Smaller numbers of the aircraft are operated by some 9 other airlines.[1]

Accident history

The ERJ 145 family of aircraft has an outstanding service record with no reported crashes or fatalities due to mechanical malfunction. There have been a small number of reported incidents involving the ERJ 145. In one case a Rio-Sul pilot descended beyond the normal rates and landed at a speed significantly higher than the normal landing speed. This aircraft tail section bent and was dragged along the runway. In the other case, a Continental Express (ExpressJet) flight overran a Cleveland runway in blizzard conditions; there were no injuries and the aircraft was returned to service. Another ExpressJet aircraft crashed on takeoff in Beaumont, Texas during a training flight; that aircraft was a total loss, but again no injuries were sustained.

On May 2, 2006 two ERJ 145's were involved in separate incidents at two U.S. airports. The first incident involved a Continental Express jet blowing a tire on its left-side landing gear on takeoff at Bush Intercontinental Airport in Houston, Texas. The plane landed safely with no injuries.[1] The second incident involved a American Eagle flight which also blew out a tire on takeoff at Chicago's O'Hare International Airport. The plane skidded off the runway coming to rest 25 feet away in the grass. There were no injuries reported.[2].

A BA Citiexpress Aircraft overshot the runway at Hannover on landing with no injuries to passengers or crew. On June 18, 2006, another incident involved a Continental Express (ExpressJet) ERJ 145. Flight 2482 from Corpus Christi, TX (CRP) to Houston Intercontinental (IAH), made an emergency landing in Victoria, TX after an engine fire filled the lavatory and cabin with smoke. [3]
