Both the pilots on the carrier landed safely, a senior naval official said.
"The Chetak helicopter developed low oil pressure. Any variation in oil temperature of a helicopter can cause a snag. The pilots adopted emergency procedures and landed safely in South Goa," Indian Navy's Flag Officer Commanding Goa Area (FOGA) Rear Admiral Puneet Bahl told PTI.
The helicopter landed at a property owned by Lalit Group of Hotels in South Goa's Canacona village at 7.15 AM.
He said both the pilots on board Chetak were safe and they followed correct emergency procedures prescribed in such a situation.
"We have sent a team which will investigate and only after that we will come to know the exact reason for the possible snag," Bahl added.
