APPROVAL: The technical contents of this Service Bulletin have been approved by the Federal Aviation Administration (F.A.A.). PURPOSE: Recent reports indicate that the ARTEX 110-4 ELT battery packs may vent and leak acid into the battery case. This condition combined with humidity, may cause the plastic material of the EL T battery case to break down, which could result in severe cracking of the ELT battery case. ARTEX has released Product Advisory Notice No. 2 regarding this condition, which is included with this publication. In addition, should the ELT battery case crack and leak acid, the EL T attachment bracket may corrode and require replacement. Left uncorrected, the possibility exists that the EL T function may become impaired and that the EL T attachment bracket may fail due to corrosion. This Service Bulletin requires inspection per ARTEX Product Advisory Notice No. 2 to detect cracked and/or leaking EL T battery packs. In addition this Service Bulletin requires inspection of the Piper EL T attachment bracket if battery acid has leaked from the ELT battery case.
