• Regulation (EU) 2020/270 found in: Balloon Rule Book - Part-BOP Part-BFCL Part-ML CS-31GB CS-31HB CS-31TGB (Sep 2020)

Appendix III — Complex maintenance tasks not to be released by the Pilot-owner Regulation (EU) 2020/270 All of the following constitutes the complex maintenance tasks which, according to Appendix II, shall not be carried out by the pilot-owner. Those tasks shall be released either by an approved maintenance organisation or by independent certifying staff: (a)     the modification, repair or replacement by riveting, bonding, laminating, or welding of any of the following airframe parts: (1)     a box beam; (2)     a wing stringer or chord member; (3)     a spar; (4)     a spar flange; (5)     a member of a truss type beam; (6)     the web of a beam; (7)     a keel or chine member of a flying boat hull or a float; (8)     a corrugated sheet compression member in a wing or tail surface; (9)     a wing main rib; (10)    a wing or tail surface brace strut; (11)    an engine mount; (12)    a fuselage longeron or frame; (13)    a member of a side truss, horizontal truss or bulkhead; (14)    a seat support brace or bracket; (15)    a seat rail replacement; (16)    a landing-gear strut or brace strut; (17)    an axle; (18)    a wheel; and (19)    a ski or ski pedestal, excluding the replacement of a low-friction coating; (b)     the modification or repair of any of the following parts: (1)     aircraft skin or the skin of an aircraft float if the work requires the use of a support, jig or fixture; (2)     aircraft skin that is subject to pressurisation loads if the damage to the skin measures more than 15 cm (6 in.) in any direction; (3)     a load-bearing part of a control system, including a control column, pedal, shaft, quadrant, bell crank, torque tube, control horn and forged or cast bracket, but excluding: (i)      the swaging of a repair splice or cable fitting; and (ii)     the replacement of a push-pull tube end fitting that is attached by riveting; (4)     any other structure not listed in point (a) that a manufacturer has identified as primary structure in their maintenance manual, structural repair manual or instructions for continuing airworthiness; (c)      the performance of all of the following maintenance on a piston engine: (1)     dismantling and subsequent reassembling of a piston engine other than: (i)      to obtain access to the piston/cylinder assemblies; or (ii)     to remove the rear accessory cover to inspect and/or replace oil pump assemblies, where such work does not involve the removal and refitment of internal gears; (2)     dismantling and subsequent reassembling of reduction gears; (3)     welding and brazing of joints, other-than-minor weld repairs to exhaust units carried out by a suitably approved or authorised welder but excluding component replacement; (4)     the disturbing of individual parts of units which are supplied as bench-tested units except for the replacement or adjustment of items normally replaceable or adjustable in service; (d)     the balancing of a propeller, except: (1)     for the certification of static balancing where required by the maintenance manual; and (2)     dynamic balancing on installed propellers using electronic balancing equipment where permitted by the maintenance manual or other approved airworthiness data; (e)     any additional task that requires: (1)     specialised tooling, equipment or facilities; or (2)     significant coordination procedures because of the extensive duration of the tasks and the involvement of several persons.
