Rear fuselage of an aircraft comprising a tail cone end and a rest of the real fuselage whereby the tail cone end is attached to the rest of the rear fuselage by means of an attachment system comprising a balancer fitting, three lugs and a waiting link. When there is a failure in one of the lugs, the balancer fitting acts supporting loads in the transversal direction of the aircraft. The waiting link only acts if a failure in other link occurs. This waiting link is able to support loads in the longitudinal direction of the aircraft.

1. A rear fuselage of an aircraft comprising: a tail cone end and a rest of the rear fuselage whereby the tail cone end is attached to the rest of the rear fuselage by an attachment system including: a first lug,a second lug, anda third lug, which are disposed in a triangle disposition, including the first lug and the second lug disposed either in an upper portion of the rear fuselage or in a lower portion of the rear fuselage, placed at a same height and each one of the first and second lugs placed in one of lateral portions of the rear fuselage,the attachment system also including a balancer fitting disposed in between the first lug and the second lug, andthe attachment system further including an additional waiting link arranged opposite to the balancer fitting and placed below the third lug when the additional waiting link is in the upper portion and placed above the third lug when the additional waiting link is placed in the lower portion, the additional waiting link only transmits a load between the tail cone and the rest of the fuselage when one of the first, second, or third lugs fails, and the first, second, and third lugs provide an isostatic union in the attachment system. 2. The rear fuselage of an aircraft according to claim 1, wherein the first lug and the second lug support loads in a longitudinal direction of the aircraft and in a vertical direction of the aircraft (X, Z) and the third lug supports the loads in the longitudinal direction of the aircraft and a transversal direction of the aircraft (X, Y). 3. The rear fuselage of an aircraft according to claim 1, wherein the first lug and the second lug are placed in the lower portion when an APU air intake is in the upper portion. 4. The rear fuselage of an aircraft according to claim 1, wherein the first lug and the second lug are placed in the upper portion when an APU air intake is in the lower portion. 5. An aircraft comprising a rear fuselage according to claim 1. 6. A method of assembly of the rear fuselage of the aircraft defined in claim 1, comprising: installing the balancer fitting;installing the first lug and the second lug;installing the third lug; andinstalling the waiting link. 7. The rear fuselage of an aircraft according to claim 1, wherein no more lugs than the first, second, and third lugs are provided in the attachment system. 8. The rear fuselage of an aircraft according to claim 1, wherein the additional waiting link is disposed within the triangle disposition of the first, second, and third lugs. 9. The rear fuselage of an aircraft according to claim 1, wherein the balancer fitting only transmits a load between the tail cone and the rest of the fuselage when one of the first, second, or third lugs fails. 10. The rear fuselage of an aircraft according to claim 1, wherein the balancer fitting is a guide for the tail cone to position the tail cone for assembly with the rest of the rear fuselage.
