(1)
Each pilot seat must be designed for the reactions resulting from the applica-tion of the pilot forces prescribed in Sec. 29.397; and

(2)
TheinertialforcesprescribedinSec.29.561(b) mustbe multipliedby afactor of 1.33 in determining the strength of the attachment of–

(i)
Each seat to the structure; and

(ii)
Each safety belt or harness to the seat or structure.

(g)
When the safety belt and shoulder harness are combined, the rated strength of the safety belt and shoulder harness may not be less than that corresponding to the inertial forces speci.ed in Sec. 29.561(b), considering the occupant weight of at least 170 pounds, considering the dimensional characteristics of the restraint system installation, and using a distribution of at least a 60-percent load to the safetybelt and atleasta40-percentload tothe shoulderharness.If the safetybelt is capable of being used without the shoulder harness, the inertial forces speci.ed must be met by the safety belt alone.

(h)
When aheadrestis used, theheadrestandits supporting structure mustbedesigned to resist the inertia forces speci.ed in Sec. 29.561, with a 1.33 .tting factor and a head weight of at least 13 pounds.

(i)
Each seating device system includes the device such as the seat, the cushions, the occupant restraint system and attachment devices.

(j)
Each seatingdevice system may usedesignfeatures such as crushing or separation of certain parts of the seat in the design to reduce occupant loads for the emergency landing dynamic conditions of Sec. 29.562; otherwise, the system must remain intact and must not interfere with rapid evacuation of the rotorcraft.

(k)
For purposes of this section, a litter is de.ned as a device designed to carry a no-nambulatoryperson,primarilyinarecumbentposition,into and onthe rotorcraft. Each berth or litter must be designed to withstand the load reaction of an occu-pant weight of atleast170pounds whenthe occupantis subjectedtotheforward inertial factors speci.ed in Sec. 29.561(b). A berth or litter installed within 15' or less of the longitudinal axis of the rotorcraft must be provided with a padded end-board, cloth diaphragm, or equivalent means that can withstand the forward load reaction.Aberth orlitter orientedgreaterthan15'with the longitudinal axis of the rotorcraft must be equipped with appropriate restraints, such as straps or safety belts, to withstand the forward reaction. In addition–

(1)
The berth or litter must have a restraint system and must not have corners or other protuberances likely to cause serious injury to a person occupying it during emergency landing conditions; and

(2)
The berth orlitter attachment and the occupant restraint system attachments to the structure must be designed to withstand the critical loads resulting from .ight and ground load conditions and from the conditions prescribed in Sec.29.561(b).[The .ttingfactorrequiredbySec.29.625(d) shallbeapplied.]

FAR 29.787 : Cargo and baggage compartments.
(a)
Each cargo and baggage compartment must be designed for itsplacarded maximum weight of contents and for the critical load distributions at the appropriate maxi-mumloadfactorscorresponding tothespeci.ed .ightandgroundload conditions, except the emergency landing conditions of Sec. 29.561.

(b)
There must be means to prevent the contents of any compartment from becoming ahazardby shifting undertheloads speci.edinparagraph(a) ofthis section.

(c)
Underthe emergencylanding conditionsofSec.29.561,cargoandbaggagecompart-ments must–

(1)
Be positioned so that if the contents break loose they are unlikely to cause injury tothe occupants orrestrictany of the escapefacilitiesprovidedforuse after an emergency landing; or

(2)
Have su.cient strength to withstand the conditions speci.ed in Sec. 29.561, including the means of restraintand their attachmentsrequiredbyparagraph
