12.6.4.D‐Structuralinspection
Astructural inspectionis requiredto verify the structuralsoundnessof critical
componentsoftheaerialplatformandmustbeperformed:
1 10yearsafterthedateofmanufactureandevery5yearsthereafter
2 Aftereveryaccidentthatmayactually,presumably, orpotentiallycauseda‐
mage and affectthe structural sou
ndness or stability of the aerial plat form.
Suchaccidentsincludeshortcircuits,impacts,falls,collisions,orcasesofover‐
stressorstabilityfailure.
3 Afterachangeofownership,unlessacompleteservicehistoryisprovided,in‐
cludingmaintenanceandinspectionrecords.
Thestructural ins pectionmustbe carriedoutunderthesupervisionofaprofes‐
sionalengineer
.
Thisinspectionmust:
1 Considertheservicehistoryof theaerialplatformintermsofhoursofservice,
severityofuse,andnumberandvariabilityofusers;
2 Reviewtheinspectionand maintenancerecordoftheaerialplatform;
3 Verifytheefficiencyofalloperatingcontrols;
4 Performavisualinspectionoftheaerialplatform;
5 Consider recommendatio
ns of the manufacturer regarding the aerial pla‐
tform,including manufacturerʹssafetybulletins.
12.6.5.E‐Maintenance
Beforeadjustmentsandrepairsarestartedontheaerialplatform,thefollowing
precautionsmustbetaken:
1 Thepowersystemmustbestopped,andthestartingdevicesmustberende‐
redinoperative;
2 Al
lcontrolsmustbeintheOFFpositionandalloperatingsystemsmustbese‐
curedagainstaccidentalactivationbybrakes,chocksorothermeans;
3 Elevatingandrotatingassemblyandplatformmustbecompletelylowered,if
possible,orotherwisesecuredbyblockingorpropping;
4 Thehydraulicoilpressuremustbereleasedfromallhydr
auliccircuitsbefore
looseningorremovinghydrauliccomponents;
5 Safetypropsorlatchesmustbeinstalledwhereapplicable;
6 Otherprecautionsmustbeadoptedasspecifiedintheuserandoperationma‐
nual.
